The Summer Undergraduate Research Fellowship (SURF) Symposium
In recent years, commercial computer systems have grown more user friendly, allowing for new users to quickly and easily make contributions. Unfortunately, this trend is not as apparent in the field of computational materials simulations. The tools used by researchers in this field have remained just as esoteric as the systems of the past. While the methods used in materials simulations continue to grow in complexity and accuracy, the user experience has been neglected entirely. This project aims to eliminate the need for hours spent adjusting file formats and searching for preexisting code, and instead allow researchers to focus on …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Crystalline Nano-cellulose (CNC) is a general molecular structure obtained from acid hydrolysis of native fiber. They are often very short (100 to 1000 manometers) and the mechanical properties of CNC varies depend on length scale. Due to defect formation of the structure, the mechanical properties of the material composed of such CNC may vary drastically. This study was to provide a numerical tool to integrate a few valid modules and to better understand the mechanical properties of CNC and the overall performance of the bio-inspired material composed of CNC. Our focus is mainly on two type of composite structure [1] …

The Summer Undergraduate Research Fellowship (SURF) Symposium
MEMS (Micro-electromechanical System) is a combined electrical and mechanical nano-scaled device with rapidly growing applications. We have developed a contacting radio frequency capacitive MEMS that is commonly used as capacitive switches and contact actuators in PRISM (Prediction of Reliability, Integrity and Survivability of Microsystems) lab at Purdue University. Our research team has focused on creating a simulation of MEMS’s survivability towards crazing and cracking. Our particular objective in this project is to create a tool that can help users perform complex quantitative calculations regarding the properties of different materials. This tool will generate various plots visualizing the properties, such as …

The Summer Undergraduate Research Fellowship (SURF) Symposium
The Stanford Stratified Structure Solver (S4) developed in 2012 allows for fast, accurate prediction of optical propagation through complex 3D structures. However, there have been two key challenges preventing wider use to date: the use of a specialized control language, and the difficulty of incorporating realistic materials parameters. In this project, both concerns have been addressed. We have constructed a graphical user interface as an alternative, using the open-source Rappture platform on nanoHUB. This has been combined with a comprehensive materials database known as PhotonicsDB, which incorporates materials optical data drawn from carefully vetted sources. An Octave script file was …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Microelectromechanical Systems (MEMS) are systems made up of small components to complete a bigger goal. Some of these components can be modeled as small beams, which are anchored at both sides, or as cantilever beams. These beams can be subjected to various forces such as Knudsen Forces, Electrostatic Forces as well as G-loading. These devices have many applications such as sensors, actuators and even as accelerometers for airbags, smart phones and game controllers. Modeling the dynamics of these beams is an important task for the MEMS community, consisting of researchers, fabricators, and designers working on one of the many applications …
