Fracture Mechanics

AAE65400

Credit Hours: 3

Learning Objective:
At the end of course the students will have fundamental understanding of the following: Introduction to the mechanics of fracture of brittle and ductile materials. Linear elastic fracture mechanics; elastic-plastic fracture; fracture testing; numerical methods; composite materials; creep and fatigue fracture.

Description:
The objective of this course is to provide students with an introduction to the mechanics of fracture of brittle and ductile materials. Lectures will focus on the basics of linear-elastic fracture mechanics (LEFM) and elastic-plastic fracture mechanics (EPFM) including the J-Integral. Time dependent fracture including creep and fatigue crack growth will be covered. Methods to experimental determine fracture properties (ASTM standards) will be introduced. Spring 2017 Syllabus PDF.

Topics Covered:
Basic fracture mechanics, atomic view of fracture, Griffith energy criterion, energy release rate R and driving force curves, stress analysis, crack tip plasticity, mixed mode fracture, crack tip opening displacement, J Integral, J-CTOD relationships, crack growth resistance curves, J controlled fracture,dynamic fracture, rapid crack propagation/arrest, creep crack growth, ductile/brittle failure, intergranular fracture, failure in polymers, fracture in ceramics, experimental fracture testing methods, elastic-plastic testing methods, dynamic testing, fracture testing of polymers, testing of composite and ceramics, stress corrosion cracking, hydrogen embrittlement.
