E. Markiewicz et al., Calculation of the deep bending collapse response for complex thin-walled columns - II. Pre-collapse phase, THIN WALL S, 33(3), 1999, pp. 177-210
The increasing complexity of transport vehicles means that more powerful fi
nite element models are needed to simulate their crash behaviour. The struc
tures cannot be effectively optimized, in terms of peak moment and energy m
anagement, by these models which require long calculation times and should
only be used as a final verifying tool. Distinct kinematic models have been
developed to analytically determine the resistance to collapse of thin-wal
led structures subjected to bending loading. Part II of this paper concerns
the theoretical prediction of bending strength in the post-failure range f
or thin-walled structures of relatively complex geometry with a floating ne
utral axis position. It also concerns the validation of the proposed genera
lized bending kinematic model with experimental results, numerical results
and results of published literature. For all cases considered, the analytic
al solution was shown to predict the moment-rotation relationship with an e
rror generally below 15%. (C) 1999 Elsevier Science Ltd. All rights reserve
