Influence of mesh type and size on crack growth modeling
Finite element simulation of fatigue crack propagation is studied. In this work, we use the fatigue constants and cyclic plasticity material properties from tests were used during simulation to predict fatigue crack propagation. We examine the effect of the mesh type and size that used in the finite element model on the predicted crack growth rate was examined. It shows that the crack propagation behavior is quite different from each other, as mesh size comes smaller or use different mesh type of finite element simulation the crack propagation behavior is quite different compared. The simulation results of eight-node plane-stress and the mesh size between 230μm and 260μm accord with the experiment results for carbon manganese steel 16MnR.
