Dr. Pedro Peralta, a Professor for the School of Mechanical and Aerospace Engineering of the Ira A. Fulton Schools of Engineering has a research opening for the following project:
Damage behavior at large pressures and strain rates plays a key role on performance of a wide range of armor and other protection systems to guard against blast and ballistic impacts, which pose a significant threat to military, law enforcement and homeland security personnel and vehicles. Understanding the mechanisms for damage nucleation and growth is key to develop reliable models to estimate and predict the performance of these systems. One key aspect is the speed at which damage evolves under dynamic loading. In this project, simulations of spherical and polyhedral voids, shapes observed experimentally, will be performed using finite element models to simulate the interaction between these voids and shock waves using models for material response developed specially for this application. A comparison between void growth under dynamic and quasi-static loading needs to be performed and effects of inertia on the kinetics of void growth need to be evaluated.
- Ballistic impact
Candidates need to be proficient with solid modeling. Experience with finite elements will be a large plus, e.g., those who have taken finite element courses (Finite elements for engineers, non-linear finite elements). Undergraduate students must have passed MAE 213 with a grade of A and be taking MAE 322 or AEE 325. Graduate students must have passed MAE 529 (preferred) or MAE 520 with a grade of A.At least 3.5 GPA. Mechanical or aerospace engineering students only.
