3Learning 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:
Fracture Mechanics: Fundamentals and Applications, Fourth Edition is the most useful and comprehensive guide to fracture mechanics available. It has been adopte Benz. In this paper, we present the implementation of a small library of three-dimensional cohesive elements. The elements are formatted as user-defined elements, for compatibility.

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.
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.Applied / Theory:
