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.

Numerical Simulation of UHMWPE Laminated Fiber Plate Resisted Projectile

The problem of UHMWPE laminated fiber plate resisted projectile was studied by the non-linear FEM that Truegrid/LS-Dyna. The material parameters of fiber layers were gained after synthesizing test datum and some references, then the model of *MAT_COMPOSITE_DAMAGE was used to simulate the UHMWPE laminated fiber plate. The results of numerical simulation were compared with the test results, and the method of numerical simulation in the paper was proved.

Grain distributions on fatigue crack initiation in a notched coarse grained superalloy specimen

This study uses Monte Carlo simulations to investigate how random grain structures in coarse-grained superalloys affect the fatigue life of notched components. The results demonstrated a significant and non-negligible variation in life, concluding that this scatter must be considered in industrial applications and cannot be captured by traditional analysis.

Modeling the sound of a golf club impact

This study uses computer simulations (FEM and BEM) to predict the sound produced by a golf driver hitting a ball. The simplified model's simulated vibration modes were slightly lower than experimental measurements due to removed features, but the simulation accurately predicted acoustic modes in unaltered areas and on a fully-featured test plate.

Friction Induced Damage: Preliminary Numerical Analysis of Stresses Within Painted Automotive Plasti

D.J. Mihora and A.C. Ramamurthy

This research uses finite element analysis to compare subsurface stresses within painted automotive plastics caused by sliding contact. The study provides insights into friction-induced damage and aids in the development of a testing device.
