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.

As-Built Model Generation for a Cylindrical Test Object

D. H. Chambers, D. M. Goodman, R. R. Leach

This paper outlines a method for creating an "as-built" finite element model of an object by using data from multiple nondestructive evaluation techniques. The resulting model, which captures the object's actual geometry and material properties, provides a more realistic and accurate foundation for finite element analysis than a traditional idealized model.

Helmet Impact Simulation Benefits from Foam Material Data

Joe Metrisin and Steve Pilz

This paper demonstrates the crucial role of finite element analysis (FEA) and accurate material data in virtual product development for protective equipment. Using an FEA simulation of a bicycle helmet impact, the study illustrates how this approach can predict real-world outcomes, such as a skull fracture, to inform design improvements.

Improvements to the Weak-Post W-Beam Guardrail

Klas Erik Engstrand

The paper details the redesign of a weak-post w-beam guardrail to improve its crashworthiness for larger vehicles, specifically pickup trucks. The research leverages finite element simulations to test design modifications, predict outcomes, and validate solutions before conducting costly and time-consuming full-scale crash tests.

Analise Numerica, Teorica e Experimental de Ligacoes Viga Mista-Pilar

This paper uses finite element analysis to study composite beam-to-column connections, particularly those with web and seat angles. The numerical models, created with software like TRUEGRID and ANSYS, simulate all connection components to evaluate their structural behavior under loading and compare the results with design standards.
