TY - EJOU AU - , TI - A New Theory of Strain Hardening and its Consequences for Yield Stress and Failure Stress T2 - Computers, Materials \& Continua PY - 2015 VL - 47 IS - 1 SN - 1546-2226 AB - A new theory of strain hardening is developed. Important in its own right, the strain hardening solution is also of decisive use in rigorously defining the historically broad concepts of yield stress and failure stress. Under ideal conditions yield stress is found to represent a 3rd order transition. Failure stress is an explicit "failure of function" criterion rather than just being the primitive notion of breaking into pieces. Computational extensions and opportunities are discussed.
