In this article, a new continuum damage modeling approach of “successive initiation” is used to determine the location of a thermomechanical fatigue crack initiation and the propagation path and rate in piles of integral abutment bridges. A global-local modeling approach is introduced to determine the critical location in the pile where a crack is initiated using a 3-dimensional nonlinear finite element model and to implement “successive initiation.” A simulated case study is used to showcase… CONTINUE READING
