Fracture mechanics is an interdisciplinary subject that predicts
the conditions under which materials fail due to crack growth. It
spans several fields of interest including: mechanical, civil, and
materials engineering, applied mathematics and physics. This book
provides detailed coverage of the subject not commonly found in
other texts.

Analytical Fracture Mechanics contains the first analytical
continuation of both stress and displacement across a
finite-dimensional, elastic-plastic boundary of a mode I crack
problem. The book provides a transition model of crack tip
plasticitythat has important implications regarding failure bounds
for the mode III fracture assessment diagram. It also presents an
analytical solution to a true moving boundary value problem for
environmentally assisted crack growth and a decohesion model of
hydrogen embrittlement that exhibits all three stages of
steady-state crack propagation.

The text will be of great interest to professors, graduate
students, and other researchers of theoretical and applied
mechanics, and engineering mechanics and science.
