Crashworthiness Analysis of Thin-Walled Square Columns with a Hole Trigger

Publikováno v: Materials; Volume 16; Issue 11; Pages: 4196

Thin-walled structures dynamically loaded with an axial force are the subject of this study. The structures work as passive energy absorbers by progressive harmonic crushing. The absorbers were made of AA-6063-T6 aluminum alloy and subjected to both

Neural Networks in Crashworthiness Analysis of Thin-Walled Profile with Foam Filling

Autor: Michał Rogala

Publikováno v: Advances in Science and Technology Research Journal, Vol 14, Iss 3, Pp 93-99 (2020)

This article presents numerical tests of thin-walled compressed columns with square cross-section. Crush efficiency indicators were determined using finite element method (Abaqus) and neural networks of MLP. The models had a constant circular trigger
