Self-contained treatment supplements standard texts by focusing on analytical methods for determining crack-tip stress and strain fields. Topics include solution technique for second-order nonlinear partial differential equation governing a mode I elastoplastic crack problem, plastic zone transitions, environmental cracking, and small-scale yielding versus exact linear elastic solutions.
