Large plastic strains in the problem of high-speed loading of an aluminum ribbon

详细

A method for numerical simulation of the motion of the plane liner in a magnetic compressor based on a combination of the transverse and longitudinal two-dimensional models is proposed. The method permits modeling the interaction of the liner ribbon with the rigid basement for the liner kinematic characteristics close to the experimental ones. Three different model are considered to justify the choice of the mathematical model of an elastoplastic body which would be suitable for solving similar problems. A series of computations is performed, and the results and scope of each of the models are analyzed.
