Investigation Of The Design And Static Behavior Of Cylindrical Tubular Composite Adhesive Joints Utilizing The Finite Element Method And Stress-Based Failure Theories, Michael D. Lambert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The stress and strength behavior of cylindrical tubular adhesive joints composed of dissimilar materials was explored. This was accomplished with the finite element method (FEM) and stress-based failure theories. Also, it was shown how a design of experiments (DOE) based method can be used to objectively organize the process of optimizing joint strength by using stress-based failure criteria.

The finite element program used in this work was written in-house from scratch to implement the FEM for the purpose of solving both axisymmetric and three-dimensional linear elastic governing equations of static equilibrium. The formulation of the three-dimensional model is presented, and …

Integrating Engineering Design Challenges Into Secondary Stem Education, Ronald L. Carr

Publications

Engineering is being currently taught in the full spectrum of the P-12 system, with an emphasis on design-oriented teaching (Brophy, Klein, Portsmore, & Rogers, 2008). Due to only a small amount of research on the learning of engineering design in elementary and middle school settings, the community of practice lacks the necessary knowledge of the trajectory of students' learning progressions towards design mastery and expertise and the appropriateness of otherwise established design pedagogies. The issue is even more pressing since many states are embedding engineering into their standards without a clear notion of how engineering (often conceptualized as design) works …
