Approaches such as changing the cell number, rib direction, and adding internal structure are utilized to acquire a multi-cell thin-walled structure, these approaches have meaningful effects on crashworthiness performance of tubes. In this study, comprehensive review is done by using comparing together under quasi-static three-point bending conditions. A different indicator better for each prod...

In real crash cases, simple bending behavior is not common. this case, using the three-point test to examine provides a closer simulation in terms of representation structure under loading. It seen literature that products with tube sections are generally used as door im-pact beams. On other hand, when examining developed high strength steels, it studies on profiles only evaluated hydroforming....

Curved aluminium extrusions are applied in a wide range of industrial applications. Because initially straight, an additional process is required to curve the product. Undesired wrinkling plate part at inner radius frequently observed during curving process. Wrinkling has already been extensively studied for rotary-draw bending This paper aims predicting conditions which hollow section can occu...
