WebAbaqus/Explicit is a well-established and widely used FEM solver for crash and pedestrian safety simulations. However, due to the large number of degrees of freedom, simulation time is still a ... WebThe Guyan reduction method (Reference 1) makes the assumption that the inertial forces on the O-set displacements are much less important than the elastic forces transmitted by the A-set displacements. A constraint equation for Guyan reduction can be derived by ignoring the mass terms in Equation 3. The resulting constraint equation is given by ...
