Abstract: In this paper, the constitutive relation of plasticity with strain rate and temperature dependency was used to analyse the process of crushing and impacting of structures. Computer simulations of the localisation of plastic buckling patterns and the initiation and development of adiabatic shear band were performed. The thermoplastic effects were investigated and discussed.

Keywords: buckling; impact; shear localisation; thermal plasticity.
