Course Objectives
The course will emphasize the important features of low velocity collision of members. It gives the fundamental differences from quasi-static approach to the problems. The course is specifically designed to teach the importance and necessity of knowing the effects of elastic stress waves created in bodies due to collisions.
Course Content
Stereomechanical impact. Stress waves in solids. Elementary stress wave theory. Applications of elementary one dimensional stress wave theory. Momentum traps. Spalling in bars and flat plates. Fracture with stress waves in bars. Impulsive loading of frames. Penetration. Perforation of solids. (F)
Course Learning Outcomes
At the end of the course, students will be able to
1. understand the difference between the quasi-static and dynamic properties of materials.
2. one-dimensional elastic-plastic stress waves propagating in bars.
3. improve their knowledge on how bars respond to Impact Loading which creates elastic stress waves in members.
4. analyze the contact duration between impinging bodies.
5. determine the coefficient of restitution between impinging bodies.
6. analyze stress distribution in bodies up to separation time.
7. analyze energy and momentum transmission between impinging bodies.
8. learn how to prepare, submit and present a detailed technical report on an assigned subject.
