WebJun 20, 2024 · It is mentioned that the Cauchy stress tensor can be split into a sum of two other tensors: hydrostatic pressure π and deviatoric stress. Hydrostatic pressure is defined as the mean of the normal stresses. Deviatoric stress tensor is what we get when we subtract a tensor with the pressure on diagonal from the original Cauchy stress tensor.
