Effect of T-stress on Fracture of a Long Cracked Plate in Unsteady Heat Transfer

In order to accurately predict the structure fracture caused by thermal load, a modified maximum tensile stress (MTS) criterion combined with T-stress is proposed. The modified MTS uses a two-parameter model (stress intensity factor K and T-stress) to describe the fracture behavior under thermal loa...
