Catalogue of the numerical solutions for SEN(B) specimen assuming the large strain formulation and plane strain condition

Graba M.

Archives of Civil and Mechanical Engineering

Vol. 12, no. 1

29--40

In this paper the values of the maximum opening stress and its distance from crack tip determined for various elastic–plastic materials for single edge notched specimens in bending (SEN(B)) are presented. The influence of the yield strength, the work-hardening exponent and the crack length on the maximum opening stress was tested. The numerical results were approximated by the closed form formulas. In this paper some comments and suggestions about modeling FEM assuming large strain formulation are given.
