Could I use C3D8R element instead of C3D8 to reduce simulation time in Abaqus ?

I am doing an FE simulation of a polycrystal ( uniaxial). I currently am using C3D8 elements to simulate the same. I would like to reduce the simulation time, Hence I am planning to use a C3D8R (...

How do we intutively understand the elastic spin tensor (We) and plastic spin tensor (Wp) in the framework of crystal plasticity ?

We know that the velocity gradient L = F'F-1 [ F ' is the time derivative of F ] Using multiplicative decomposition, F =FeFp we have , L = F'eFe -1 + Fe F'p Fp -1 Fe -1 = Le + Fe Lp Fe...
