Optimization of inelastic annular plates with cracks
Stepped plates made of a fibre-reinforced composite material are studied. The plates are subjected to the initial impulsive loading, which imparts the plates given kinetic energy. Optimal designs corresponding to the minimum of the maximal residual deflections are established making use of the variational methods of the theory of optimal control. Maximal deflections are evaluated with the method of mode form motions.
