 doi:10.1016/j.jmps.2007.03.009

Mechanism-based discrete dislocation
plasticity is used to investigate the effect of size on micron scale
crystal plasticity under conditions of macroscopically homogeneous
deformation. Long-range interactions among dislocations are naturally
incorporated through elasticity. Constitutive rules are used which
account for key short-range dislocation interactions. These include

Sliding motion simulation

Is it possible to simulate the sliding motion between master and slave surfaces and extract the inertia forces exerted by the master surface motion transferred on to the slave surface similar to

 

we have one machine base on which mass will slide with a certain velocity,due to friction between linear motion guides and mass,inertia force will be transmitted to the base,
