Analysis of thruster nozzle in a high-temperature environment using partitioned coupling framework to combine a kinematic hardening plasticity model and a creep model

Abstract

A framework based on a partitioned stress integration technique was proposed by the present authors for a general combined elastic-plastic and creep constitutive model. It was developed to analyze a structure used in a high temperature environment. In the present study, a thruster nozzle model subjected to thermal strain is analyzed using the framework to verify it. The Ohno-Wang model and the Norton-Bailey model are used for the elastic-plastic model and the creep model, respectively. This combined model is also verified..
