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.

Experimental Testing and Numerical Modeling of Soil-Filled Concertainer Walls

K. Scherbatiuk and N. Rattanawangcharoen

This study uses a finite element model to predict the behavior of soil-filled concertainers under blast loading. The model's results are validated against full-scale experimental data to ensure accuracy and provide insight into the failure mechanism of the protective structures.
