A study of plastic waves during dynamic buckling of ductile slabs
(2002) In Modelling and Simulation in Materials Science and Engineering 10(5). p.569-580- Abstract
- Plastic wave propagation is studied during progressive plastic buckling of elastic viscoplastic slabs. The numerical results of the buckling behaviour are studied using two recent approaches for monitoring the plastic wave propagation. One method is a direct geometrical monitoring of the waves using a sequence of smooth approximations (geo-plot). The other method is a contour plot method (q-plot) where contours of the normalized inelastic strain rate are used. The field quantities are obtained using a non-linear finite element method in the analysis of the dynamic viscoplastic buckling problem. The numerical results show that both methods are well suited for describing plastic wave motion and that the simpler q-plot method is fully... (More)
