A Method for Modyfying the Forming Tool Geometry in Order to Compensate for Springback Effects

Anders Jernberg

This paper introduces a heuristic method for compensating for springback in metal forming by modifying the forming tool's geometry. It demonstrates an iterative process using LS-DYNA to simulate forming and springback, applying finite element analysis to iteratively adjust the tool's shape and achieve the desired final product geometry.

Variable Force Energy Dissipater and Decelerator

September 12, 2050// Malcolm H. Ray and Chuck A. Plaxico

This patent describes a variable force energy dissipater and decelerator that uses finite element analysis to predict and refine its performance under impact conditions. The simulations demonstrate how the device controls deceleration by tailoring energy absorption to reduce peak forces and improve safety.

Rimantas Barauskasa, and Ausra Abraitiene

This paper details the development and validation of a finite element model in LS-DYNA for simulating the ballistic impact of a bullet on multi-layer fabrics, highlighting the role of finite element analysis in simplifying complex physical interactions.

Refined 3D Finite Element Modeling of Partially Restrained Connections Including Slip

A.M. Citipitioglu, R.M. Haj-Ali, D.W. White

This paper introduces a sophisticated parametric 3D FEM approach for analyzing partially-restrained bolted steel beam-column connections. It examines how varying geometrical and material parameters, including critical aspects like bolt pretension and slip, influence the connection's complex nonlinear behavior. The developed versatile modeling technique, which employs parametric meshing, enables accurate prediction and extensive parametric studies for a broad spectrum of connection designs.
