Numerical simulations of plane strain tension for nickel-based alloy 718

Abstract

: The analysis of possible approaches to the numerical simulation of tensile flat specimen made from 718 superalloy is presented. Three plasticity models were employed, with various numbers of material parameters and, therefore, complexity. The influence of simplifying the three-dimensional geometry into the plane was researched in the view of force response, deformation and stress state in the crack initiation location, which was in the centre of the specimen.
