Abstract EN
Based on the assumption of quasibrittle failure under high-cycle fatigue for the metal material, the damage constitutive equation and the modified damage evolution equation are obtained with continuum damage mechanics.
Then, finite element method (FEM) is used to describe the failure process of metal material.
The increment of specimen’s life and damage state can be researched using damage mechanics-FEM.
Finally, the lifetime of the specimen is got at the given stress level.
The damage mechanics-FEM is inserted into ABAQUS with subroutine USDFLD and the Python language is used to simulate the fatigue process of titanium alloy specimens.
The simulation results have a good agreement with the testing results under constant amplitude loading, which proves the accuracy of the method.
