That is, the locations on the structure where inertia forces are large compared to elastic forces are to be retained. 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 ... uhmw for boats
