Plastic wave propagation in ductile slabs subjected to dynamic buckling
(2003) Mathematical Modelling of Wave Phenomena 2002 Mathematical Modelling of Wave Phenomena 2002. p.207-215- Abstract
- Plastic wave propagation during dynamic buckling of ductile slabs is investigated numerically using a contour plot method (q-plot) showing contours of normalized effective plastic strain rate as a function of time and position. A non-linear finite element method is used to analyse the buckling problem of the elastic-viscoplastic slab. The contour plot method is quite sufficient to depict the overall development of the localization zones. Wave propagation speeds, relative growth of the localization zones and displacement of non-stationary in-elastic waves may be investigated. The present study also indicates that certain buckling modes may be promoted by selecting particular initial specimen geometries.
