Fracture mechanics

ME-432

Lecturer(s) :

Botsis John
Cugnoni Joël

Language:

English

Remarque

Course reserved for Mechanical Engineering students.

Summary

The student acquires the notions of damage and fracture in different materials; the basis of energy release rate and stress intensity factor; fracture criteria; weight functions for crack opening displacements; J integral and non-linear fracture; fatigue crack propagation.

Content

The course presents the modern theory of fracture mechanics, stress singularities, the various fracture modes, stress intensity factors and energy release rates in linear and no-linear materials. The main chapters cover the following topics: review of the classical theories of strength and damage, singular problems in linear elasticity theory and fracture parameters, weight functions, fracture in elastoplastic materials, applications to composite materials, experimental methods in fracture mechanics.
