Abstract
Constitutive equations of viscoplasticity belong to the most complicated ones, hence optimal design of viscoplastic structures is usually performed in a purely numerical way, and the use of suitable discretization methods is necessary. In the present paper finite element method is used for optimal design of a rigid-viscoplastic bar under the impact of anial force. Minimal residual displa-cement is assumed as the design objective under the constraint of constant volume of the bar. Finite strains are allowed for and various shapes of force impulse are considered. Optimization of viscoplastic I-beams under dynamic loadings is also mentioned.
