Dear all,
I want to define cohesive surface in my model which is a polycrystalline of Titanium with its grains. Can anyone help me that How I should find the appropriate values for fracture energy and mode mix ratio 1 and 2?
For damage initiation, what do I consider for normal, shear 1 and shear 2 in contact property of interaction module? Are Tensile and shear strength suitable for these properties?
Thank you
