A Finite Element Model Based On Coupled Refined High-Order Global-Local Theory For Static Analysis Of Electromechanical Embedded Shear-Mode Piezoelectric Sandwich Composite Beams With Various Widths, S.B. Beheshti-Aval, S. Shahvaghar-Asl, M. Lezgy-Nazargah, Mohammad N. Noori
Mechanical Engineering
In this study, a new theory for the accurate simulation of the shear-mode behaviour of thin or thick piezoelectric sandwich composite beams is developed. The effects of transverse normal stress and transverse flexibility of layers are considered in the development of the proposed formulation. In order to increase the computational accuracy, all kinematic and stress continuity conditions are satisfied at layer interfaces. Moreover, for the first time, both the electrically induced strain components and the transverse flexibility are taken into account in the proposed formulation. Despite the fact that the number of unknown mechanical parameters in this theory is only …

Workshop A - Implementing The "Design Your Process Of Becoming A World Class Engineering Student" Project, Steffen Peuker, Raymond B. Landis
Mechanical Engineering
Many students come into an engineering program lacking a strong commitment to stay in an engineering program and to graduate with an engineering degree. For students to accomplish the challenging goal of graduating in engineering requires a strong commitment, and behaviors and attitudes to follow through that commitment. To strengthen the commitment of the freshman engineering students an innovative project has been developed. The project challenges students to develop their process to become a "World-Class Engineering Student". Having freshman engineering students design their individually tailored learning process as part of a semester long project in the setting of a student …

Implementing Team Based Learning In Freshmen Engineering Courses, Steffen Peuker, Jennifer Peuker
Mechanical Engineering
Team Based Learning (TBL) is a specific pedagogical tool that emphasizes collaborative learning. Oftentimes TBL is confused with group activities and other active learning strategies involving student teams. TBL is distinct because it follows a prescribed sequence of individual work and group work, and includes immediate feedback as well as peer evaluation. TBL is widely used in medical, pharmacy and nursing schools and the use of TBL in engineering education is growing. The advantages of using TBL in the class room include: (1) students are held accountable for individual (pre-class) and group (in-class) work. (2) The responsibility for learning shifts …

SOFIA, the world’s largest airborne observatory with 2.5-meter diameter infrared telescope is equipped with 7 instruments: EXES, FIFI-LS, FLITECAM, FORCAST, GREAT, HAWC, and HIPO. Flying at altitudes between 39,000 and 45,000 feet, SOFIA avoids 99% of the atmospheric water vapor, records and analyzes the infrared radiation from the cosmos. SOFIA is able to observe the occultation of stars by solar system objects. By determining the size, compositions, and atmospheric structures of these objects, SOFIA can help answer the questions on creation and evolution of the universe, formation of the stars and planets, and nature of black hole at the center …
Characterization Of The Drilling Via The Vibration Augmenter Of Rotary-Drills And Sound Signal Processing Of Impacted Pipe As A Potential Water Height Assessment Tool, Nicholas Morris
STAR Program Research Presentations
The focus of the internship has been on two topics: a) Characterize the drilling performance of a novel percussive augmenter – this drill was developed by the JPL’s Advanced Technologies Group and its performance was characterized; and b) Examine the feasibility of striking a pipe as a means of assessing the water height inside the pipe. The purpose of this investigation is to examine the possibility of using a simple method of applying impacts to a pipe wall and determining the water height from the sonic characteristic differences including damping, resonance frequencies, etc. Due to multiple variables that are relevant …
Finite Element Models Of The Knee & Hip Joints: Using Opensim To Predict Muscle Forces, Kevin S. Jones, Spencer D. Wangerin, Jeffrey D. Pyle, Stephen M. Klisch, Scott J. Hazelwood
Finite Element Models Of The Knee & Hip Joints: Using Opensim To Predict Muscle Forces, Kevin S. Jones, Spencer D. Wangerin, Jeffrey D. Pyle, Stephen M. Klisch, Scott J. Hazelwood
STAR Program Research Presentations
Quantitative data of stresses and strains in the cartilage of the knee and hip joints are required to design prostheses and can be used to give accurate advice to patients with cartilage damage as to which activities should be avoided. Instrumented hip implants can only give the overall resultant force in the joint, not the stresses and strains throughout the cartilage. Finite Element (FE) models of the Knee and Hip are being constructed in order to obtain the stresses and strains in articular (of the joint) cartilage. Muscle forces and joint contact forces are required as inputs to these FE …
Student Industry Cooperation For The Development Of Thermal System Design Teaching Laboratory Equipment, Steffen Peuker
Student Industry Cooperation For The Development Of Thermal System Design Teaching Laboratory Equipment, Steffen Peuker
Mechanical Engineering
In higher education, hands-on undergraduate education using state-of-the-art laboratory equipment is important to meet the quality standards expected in the engineering profession. However, the development of modern engineering laboratories is not only time consuming, but also budget constraints can hamper the development of needed laboratories for instructional purposes as Bidana and Billo state: "Development of state-of-the-art engineering laboratories is becoming an increasing problem in the University environment. Due to the greater variety and increased complexity of much state-of-the-art hardware and software, the cost and cycle time for development and startup of a modern engineering laboratory can be excessive. This, together …
Incorporating Active Learning Into A Thermal System Publications Lecture, Jennifer M. Peuker, Steffen Peuker
Incorporating Active Learning Into A Thermal System Publications Lecture, Jennifer M. Peuker, Steffen Peuker
Mechanical Engineering
Many mechanical engineering departments offer a thermal system design (or similar) course for senior students. Some courses have a laboratory component, but many are a lecture only format. This paper demonstrates how active learning—through virtual labs, a semester long project, and in-class assignments—was incorporated into the lecture portion of a thermal system design course to enhance learning and provide the students a laboratory experience without a physical laboratory. These active learning ideas can also supplement the learning during lecture for those courses which have a designated laboratory time. Anecdotal evidence of the activities indicates that students were engaged and enjoyed …
Effect Of Multiple Choice Testing On Student Performance In An Introductory Engineering Course, Jennifer M. Peuker, Jennifer Mcferran Brock, Steffen Peuker
Effect Of Multiple Choice Testing On Student Performance In An Introductory Engineering Course, Jennifer M. Peuker, Jennifer Mcferran Brock, Steffen Peuker
Mechanical Engineering
This study aims to compare student performance on introductory engineering statics material by comparing the exam scores of students who are given both multiple choice (MC) questions and constructed response (CR) questions to see whether the type of exam question makes a difference in student performance and understanding. Seventy-five students in an introductory engineering course did either a MC version or a CR version of each statics problem, resulting in MC answers and a control group of CR answers to each statics problem. The students were also polled for feedback regarding their preferences of test question format at the end …

Project Based Learning In Engineering Economics: Teaching Advanced Topics Using A Stock Price Prediction Model, Lizabeth Schlemer
Industrial and Manufacturing Engineering
A graduate level advanced engineering economics class taught at California Polytechnic State University, San Luis Obispo, includes a thorough review of time value of money, investment evaluation, inflation, risk and return, financing decisions, corporate investment strategies, risk analysis and decisions incorporating non-monetary considerations. Historically this course was taught using an advanced text where the topics were covered sequentially. A redesign of the course now includes the construction of a stock price prediction model for a company of the student’s choice. Through the model, the topics are covered and discussed in the context of the large model-building project. For instance, inflation …
