Disposal System Evaluation Framework (DSEF) Version 1.0 - Progress Report

The paper outlines the development of a framework for designing and evaluating nuclear waste repositories, using finite element analysis to perform complex thermal simulations. It validates this approach by comparing a finite element model's results to an analytical solution, demonstrating the model's viability for analyzing repository designs.

Modelling of Failure in High Strength Steel Sheets

This paper explores the use of finite element analysis to model and predict failure in high-strength steel sheets. It combines mechanical testing with FE simulations to calibrate constitutive and failure models, demonstrating the importance of computational tools in material science research.

Bow of a Barge during Its Headon Impact with a Bullnose or Cellular Structure

The paper uses nonlinear finite element analysis to simulate head-on impacts of a barge bow with rigid structures, predicting the "capping force" caused by the yielding and buckling of the barge's plates and frame. This research demonstrates how FEA can model complex structural dynamics to understand the limiting forces in a collision.

Soil Structure Interaction on Spillway Walls Adjacent to Embankments

This paper focuses on validating the LSDYNA finite element code for analyzing seismic soil-structure interaction on spillway walls by comparing numerical results to physical centrifuge experiment data. The study tests multiple nonlinear soil models within LSDYNA and uses the validated model to conduct parametric studies on wall stiffness and mass. A full 3-D finite element model of Scoggins Dam is also presented to demonstrate a practical application of the methodology.
