Finite Element Analysis of an Improved Center Crack Specimen

Abstract:

Article Preview

A new crack specimen called the diagonally loaded square plate (DLSP) containing an angled central crack is analyzed using the finite element method. The stress intensity factors and the T-stress are calculated for the new specimen in the full range from pure mode I to pure mode II. Unlike the conventional center cracked specimen under uniaxial loading, the improved specimen is able to provide pure mode II. It is shown that the effect of non-singular stress component T in the DLSP specimen is not ignorable relative to the singular stress terms, particularly for mode II dominated loading conditions.
