bibo:abstract
  • In this study we simulate the fatigue test of a compact tension specimen and obtain the displacements, stresses and strains by using the finite element method. And we examine the path independency of ΔJ integral values and compare it with ΔJ integral values calculated from load-load line displacement curve. From the results of this study, we can find that ΔJ integral show the path independence for saturated materials. We can also find that the path independency of ΔJ is not satisfied when different material is assumed near the crack tip, but the difference in ΔJ is small. And ΔJ integral values calculated from load-load line displacement is very analogous with those from integration path but always have lower values than those from integration paths. In the case of crack closing, we found that ΔJ integral values from load-load line displacement should be calculated with the load increment values based on the crack opening point. The unsaturated material is also simulated and its ΔJ shows different values according to the path, but the difference is small. (rdf:langString) (en)
