the homogeneous and stratified beams, model of an ideal rigid and plastic body, yield points, the limiting moment of deflection, structural weight, residual deflection, rational project

On the basis of model of ideal rigidly plastic material the computational method of the homogeneous and stratified beams at influence of inertial reaction of ”explosive” type is developed for multilayer hybrid beams. The method allows to define regularities of an arrangement and distribution of materials along a design at which essential decrease in residual deflections is provided.
