ME6107J – Non-Linear Fracture Mechanics


Instructors:

Credits: 3 credits

Pre-requisites: Vm 311 Strength of Materials, v256 Applied Calculus IV

Description:

Develop a deeper understanding of the basic principles in fracture mechanics.
Promote economic thinking to obtain first-order solutions of complex problems.
At the end of course the students will have fundamental understanding of the following:
1) Introduction to the mechanics of fracture of brittle and ductile materials.
2) Linear elastic fracture mechanics (LEFM);
3) elastic-plastic fracture (EPFM)
4) fracture testing methods;
5) numerical methods (Fracs2D);
6) fatigue fracture.
