Elastic-Plastic-Creep-Large Strain Analysis at Elevated Temperature by the Finite Element Method.

Abstract

This paper is divided into three parts, First, a review of currently available incremental theories of plasticity and creep constitutive models is given. Second, a formulation is presented for the non-isothermal, elastic-plastic-creep-large strain analysis by the finite element method. Third, results obtained with the AGGIE I computer program for several isothermal, elastic-creep and elastic-plastic analyses are presented. The present numerical results show good agreement with experimental and other numerical results. (Author)
