TL;DR: In this article, the authors introduced functionally graded foam (FGF) fillers to fill thin-walled structures, aiming to improve crashworthiness, where the foam density varies throughout the depth in a certain gradient.

TL;DR: In this paper, the effect of different thickness gradient patterns on crashworthiness of thin-walled structures with changing wall thickness along the longitudinal direction in a certain gradient has been investigated, and the results yielded from the optimization indicate that the FGT tube is superior to its uniform thickness counterparts in overall crashing behaviors.

TL;DR: In this article, a multiobjective robust optimization methodology is presented to address the effects of parametric uncertainties on multiple crashworthiness criteria, where several different sigma criteria are adopted to measure the variations.

TL;DR: A comparative study on the different surrogate models, such as polynomial response surface (PRS), Kriging, support vector regression (SVR) and radial basis function (RBF), which have been widely used for a variety of engineering problems, thereby gaining insights into their relative performance and features in computational modeling and design.

TL;DR: In this article, the authors compared the crashworthiness of empty circular CFRP (Carbon Fiber Reinforced Plastics) with CFRP/aluminum/steel tubes filled with aluminum foam or aluminum honeycomb under axial quasi-static crushing.
