Vertical Drop of 44-BWR Waste Package With Lifting Collars

This paper uses finite element analysis to model the structural response of a 44-BWR waste package during a vertical drop. It demonstrates the application of LS-DYNA and material modeling to evaluate stresses and ensure the package’s safety and integrity under accident conditions.

Comparison of Analytical and Physical Testing Results for the DPP-2 Shipping Package

The paper details how finite element analysis was used to design and evaluate the DPP-2 shipping package, and then compares the FEA results to physical test data to confirm the model's accuracy. This approach highlights the role of FEA in determining worst-case orientations and predicting package deformation before physical prototypes are tested.

Numerical Analysis Of Layered Flexible Structures Subjected To Impact Of Soft Core Projectile

Andrzej Morka, Piotr Kędzierski, Roman Gieleta

This paper uses the finite element method to analyze the impact of a soft-core projectile on a flexible armor package, highlighting the necessity of employing an R-adaptive mesh technique to properly model the extreme material deformation. The finite element analysis shows that while the R-adaptive method enables the simulation to run to completion, it introduces a significant mass loss artifact that must be carefully monitored and controlled to ensure the validity of the results.

LSTC Free Motion Headform User's Guide

Dilip Bhalsod, Mike Burger, Jacob Krebs

A user's guide for an FEA headform model, detailing its development and validation through calibration tests against physical impact data. It demonstrates how FEA is used to create and verify a computational tool for automotive safety simulations.

A Prediction of the acoustical Output of a Golf Driver Head Using Finite Elements

Roger Sharpe

This thesis explores the use of finite element analysis to predict the sound of a golf club impacting a ball by creating and validating a coupled FEA and boundary element method model. The study concludes that while FEA can be a powerful tool for analyzing vibrational modes and informing design decisions, accurately simulating the complex acoustical output remains computationally challenging.
