March 7, 2025//Gustavo A. Aramayo, Alex Bobrek

This study details the development and validation of a high-fidelity finite element model of the 1998 Audi A8 for crash analysis, incorporating mesh analysis, structural digitization, and impact simulations to assess crashworthiness.

Development and Validation of High Fidelity Vehicle Crash Simulation Models

S. W. Kirkpatrick, J. W. Simons, T. H. Antoun

This research presents the development and validation of a high-fidelity finite element model for vehicle crash simulations, incorporating detailed mesh analysis, structural digitization, and impact testing to enhance crashworthiness prediction accuracy.

Numerical Simulation of Structural Deformation Under Shock and Impact Loads

This paper investigates a coupled multi-solver approach using AUTODYN to evaluate structural deformation under shock and impact loads, incorporating Lagrange, Euler, ALE, and SPH solvers to enhance accuracy in modeling reinforced concrete and high-strain rate phenomena.

Topology Optimization in Crashworthiness Design

Jimmy Forsberg, Larsgunnar Nilsson

This study presents a topology optimization method for crashworthiness design, focusing on material redistribution using internal energy density (IED) in explicit finite element analysis. The approach accommodates nonlinearities like contact-impact and plasticity, refining material distribution to enhance structural efficiency under crash loads.

Numerical Investigation into the Aircraft Impact Problem on RC Structure

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

Chapter 16 presents a numerical analysis methodology for evaluating the structural response of reinforced concrete structures under aircraft impacts and high-explosive detonations. Using advanced finite element modeling, the study explores failure mechanisms, material interactions, and impact resistance across various extreme loading scenarios, contributing to improved protective designs and computational modeling techniques.
