Fracture Parameter Calculations for SENT Specimens with Two Boundary Conditions

Abstract

This paper is about finite element calculations of the Mode stress intensity factor (K1), and the T-stress (T), for single edge-notched tension (SENT) specimens. Linear elastic fracture mechanics (LEFM) is used. Four cases of traction application method and plane state (TAMPS) are considered, applied uniform load and plane stress (LS applied uniform load and plane strain (LN), applied uniform displacement and plane stress (OS), applied uniform displacement and plane strain (DN). For all cases, the material is considered to be incompressible, i.e., 0.5 is used for Poisson's ratio(v).
