ABSTRACT = {The <i>T<sub>ε</sub><sup style="margin-left:-5px">*</sup></i>  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 <i>T<sub>ε</sub><sup style="margin-left:-5px">*</sup></i>  integral, via the Equivalent Domain Integral (EDI) method with incremental plasticity. Validity of the analysis was ensured by the agreement of the <i>T<sub>ε</sub><sup style="margin-left:-5px">*</sup></i>  integral obtained on the surface (plane stress) and the plane stress values from previous studies. <i>T<sub>ε</sub><sup style="margin-left:-5px">*</sup></i>  
 was observed to decrease from the outer surface of the specimen to the more constrained mid-plane. This difference became more pronounced as the crack grew.},
