Blade cutting of thin walled structures by explicit dynamics finite elements

Analysis of Thin-Walled Structures Using Torsional-Bending Elements

In this paper a new element for analysis of thin-walled structures is presented, and the effects of secondary shear stresses on longitudinal displacements are examined. Since the Interpolation Functions are based on non-uniform torsional differential equations, the analysis of stiffness matrix is facilitated. Therefore, its ability to produce accurate results with the least number of elements i...

Explicit Dynamics Finite Element Analysis of Energy Absorption Characteristics of Thin-walled Ultrasteel Columns

UltraSTEEL material has been reported to have higher yield and ultimate strengths than plain mild steel under quasi-static loads. This project aims to study the energy absorption characteristics of UltraSTEEL thin-walled structures when subjected to axial impact loads. The numerical modelling starts from duplicating the UltraSTEEL dimpling process and defining the resultant material properties ...
