Numerical investigation through Finite Elements of Neuber’s and Molski-Glinka’s rules for calculation of elastoplastic stress and strain in notched elements

Abstract

An investigation on elastoplastic stress and strain produced at notched pieces with different geometries and material properties using Finite Elements and numerical computation software. Application of Neuber’s and Molski-Glinka’s rules directed to obtaining real stress and strain at notches from data obtained with Finite Elements models. This project sets the basis for future research on the same topic, aiming to use a similar process to obtain results in a wider variety of geometries and materials.
