Modeling the Joust

This article details a finite element model developed to simulate the ballistic impact of a deformable bullet on a multi-layer fabric package. The model was validated against physical and numerical experiments to ensure its accuracy in representing the dynamic behavior of the materials.

Cost of Sanding

Nien-Yin Chang, Brian Brady

This report examines the costs and impacts of using sand for winter road maintenance in Colorado. It utilizes finite element analysis (FEA), specifically the NIKE3D code, to simulate the physical mechanism of how sand particles become airborne from the pavement when a tire passes over them. This work helps validate field observations and contributes to a broader understanding of how sanding causes windshield damage.

Summary and Evaluation of Steel Billet Testing

This paper summarizes and evaluates a series of drop tests on a scale-model steel billet to gather data for benchmarking an impact analysis methodology. It details how finite element analysis (FEA) was used to model and simulate the test conditions, demonstrating a validated approach for estimating deceleration loads on full-size storage casks during low-velocity impacts.

Evaluation of Impact Tests of Solid Steel Billet onto Concrete Pads

This paper outlines a methodology for using finite element analysis (FEA) to evaluate impact test data from a steel billet and apply those findings to a full-scale storage cask. It details the use of the DYNA3D code to simulate low-energy tipover and side drops, demonstrating a benchmarked approach for a more realistic analysis of cask performance.

Computer Simulation of an F-4 Phantom Crashing into a Reinforced Concrete Wall

M. Itoh, M. Katayama, and R. Rainsberger

This paper describes a computer simulation of an F-4 Phantom jet crashing into a reinforced concrete wall. The study uses finite element analysis (FEA) to model the high-speed impact and the resulting structural response of the wall and the aircraft.
