For defining different softening shapes other than the available bilinear or exponential softening behaviors, Abaqus allows the functionality to provide damage variable data as a function of relative effective separation in a tabular form. For the mode-independent case, defining and generating the desired tabular data is somewhat straightforward and has several good sources of instructions. However, for the mixed-mode case, Abaqus expects us to provide the damage variable data as a function of relative effective separation, "Mode Mix Ratio", and "Mode Mix Ratio for 3D", as shown in the first screenshot. The Abaqus documentation provides the details on how to define the tabular data for the mixed-mode cases when using energy-type damage evolution (limited to linear or exponential softening), as shown in the second screenshot. However, I have not found any source of reference on how to define and generate the damage variable data for displacement-type damage evolution, considering the mixed-mode case. Would anyone please help me in this regard or share their experience and expertise?
