This technical paper describes a process for creating as-built computational models using non-destructive characterization data to improve the accuracy of finite element analysis. The authors illustrate how simulating a part with its actual, as-built features—like asymmetries or defects—can produce significantly different and more realistic results compared to simulations based on idealized, as-designed models.
This paper describes PELLPACK, a comprehensive Problem Solving Environment (PSE) for solving problems involving partial differential equations. It highlights the role of Finite Element Analysis (FEA) by detailing how the system integrates various FEA solvers, mesh generators, and parallel computing techniques to simplify complex engineering and scientific simulations.
This paper details the creation and validation of a finite element model of a guardrail terminal (MELT) for crash simulation. Using LS-DYNA3D, the model accurately replicates the complex behavior of the terminal during a vehicle impact, demonstrating how FEA can be a valuable tool for evaluating design changes without relying solely on physical crash tests.
This paper uses finite element analysis to evaluate the effects of bird strikes on aircraft composite and glass panels. By comparing Lagrangian, ALE, and SPH formulations, it demonstrates how numerical methods can predict stresses and displacements in complex impact events and guide safer design.
