P. Drazetic et al., APPLICATION OF THE GENERALIZED MIXING KINEMATIC MODEL TO THE CALCULATION OF CRUSHING RESPONSE OF COMPLEX PRISMATIC SECTIONS, International journal of impact engineering, 16(2), 1995, pp. 217-235
Impact behaviour of vehicles can be conveniently studied by means of h
ybrid numerical models using equivalent elements such as bars and non-
linear springs. Wierzbicki and Abramowicz proposed a kinematic model f
or calculating the average and instantaneous crushing force for these
macro elements. An equally simple model for the pre-collapse phase was
developed by Huang and Wierzbicki. Our objective in the present paper
is to determine the entire crushing characteristic of prismatic membe
rs consisting of plates with different wall thickness. Several example
s are worked out in which comparisons with FE calculations and experim
ental results are made.
