Abstract The Tε* integral was calculated numerically along an extending, tunneling crack front in an 8 mm thick, aluminum three-point bend (3PB) specimen, using a numerical model driven by experimentally obtained surface displacements. The model provided input to a contour integration for the Tε* integral, via the Equivalent Domain Integral (EDI) method with incremental plasticity. Validity of the analysis was ensured by the agreement of the Tε* integral obtained on the surface (plane stress) and the plane stress values from previous studies. Tε*
was observed to decrease from the outer surface of the specimen to the… More >
