Simulation of crack growth in Ni-based single crystals

S. Beretta's picture

In a cooperative research between PoliMi and UIUC we have analyzed the crack growth in Ni-based single crystals:

 Crack growth experiments analyzed with DIC had shown relatively low closure levels respect to polycrystals. Crystal plasticity simulations with WARP3D have been able to simulate closure levels consistent with the experimental ones.

Comments/suggestions about a comparison of crack growth between single and polycrystalline metals are welcome.
