Parametric analysis and multiobjective optimization for functionally graded foam-filled thin-wall tube under lateral impact

Crashworthiness analysis and design of multi-cell hexagonal columns under multiple loading cases

“…As an effective approach, surrogate modeling has been extensively applied [38][39][40][41][42][43]. Of various surrogate forms, Kriging model has proven to be particularly promising for the highly nonlinear problems [6,39,[44][45][46][47] and will be employed herein to approximate EA and F max functions for each cases. Then, the crashworthiness objectives, i.e.…”

“…As a result, thin-walled structures, especially the multi-cell columns are widely used as an energy absorber in vehicle structures. To date, substantial studies [1][2][3][4][5][6][7][8] have been conducted with differently shaped mono-cell hollow and filled tubes. It has been shown that foam-filled tubes are more efficient in energy absorption than the hollow columns.…”

Fatigue optimization with combined ensembles of surrogate modeling for a truck cab

“…The surrogate model is to construct an approximate function from a series of sampling points, which are typically determined using design of experiment (DoE) methods. In this study, 100 sets of sampling data were generated using the optimal latin hypercube sampling (OLHS) approach [16,[36][37][38][39][40][41].…”

Dynamical bending analysis and optimization design for functionally graded thickness (FGT) tube

“…Reyes et al [38] developed a material model including fracture criteria for both extrusion and foam to study the influence of material failure on bending behavior of square aluminum extrusions filled with aluminum foam. Fang et al [39] investigated and optimized the crashing behaviors of three types of functionally graded foam (FGF)-filled thin-walled structures subjected to lateral impact, and found that the FGF-filled tubes can provide better designs than the ordinary uniform foam (UF) filled counterpart.…”
