P. Drazetic et al., Calculation of the deep bending collapse response for complex thin-walled columns - I. Pre-collapse and collapse phases, THIN WALL S, 33(3), 1999, pp. 155-176
The increasing complexity of transport vehicles means that more powerful fi
nite element models are needed to simulate their crash behaviour. As existi
ng models' calculation times are long and cannot effectively optimize struc
tures in terms of peak moment and energy management, they should only be us
ed as a final verifying tool. Distinct analytical models have been develope
d to determine the resistance to collapse of thin-walled structures subject
ed to a bending load. Part I of this paper concerns the theoretical predict
ion of bending strength in the pre-failure range for thin-walled structures
of relatively complex geometry. Two types of buckling are considered: elas
tic and plastic. (C) 1999 Elsevier Science Ltd. All rights reserved.
