Optimization of dynamic plastic deformation of plates with a complex contour (English)
0 references
The authors propose a method to study dynamic deformations of ideal rigid-plastic plates with a complex contour, resting on a viscoelastic foundation. The method allows to optimize the process of pulsed forming. The optimization parameters are the amplitude of pulsed loading, viscoelastic damping coefficients of the foundation, the surface density of plate material, and the edge shape and supporting conditions on the edges. Numerical examples are given for simply- and doubly-connected plates. It is shown that different combinations of control parameters can provide the same final shape of the plate.
