The present paper is concerned with an ecient framework for a nonlinear ยฎnite element procedure for the numerical analysis of ยฎnite deformation elasticยฑplastic problems, based on a deformation theory of plasticity. Stress measures are related to Green's strains via a hyperelastic constitutive law ba
## Abstract A numerical method of the NewtonโRaphson type is presented for elastoโplastic analysis using the finite element method. The method is developed from Nadai's deformation theory and Hooke's law. Numerical examples are used to show that the method provides very rapid solution convergence.
A B S T R A C T Our theory of fatigue crack growth, which is based on the Bilby, Cottrell, and Swinden crack theory, is modified to take into account work hardening at fatigue crack tips. Iii this analysis stress rather than cumulative displacement or cumulative damage is the quantity whose critical
