Ship Shock Modelling and Simulation for Far-Field Underwater Explosion

Ship shock trials are physical tests used to evaluate a ship's ability to withstand a shock from an underwater explosion. Numerical modeling, particularly using finite element analysis, offers a cost-effective alternative by simulating the dynamic response of a ship and its components to such an event.

Design Characterization of Microwave Antenna BGA Interconnect Structure Using Test-Validated Physics

D.A. Pietila, M. Rassaian, K. Brice-Heames

Researchers evaluated a two-component solder BGA structure for attaching a microwave receiver module to a phased array antenna. They used a plastic-strain damage model and finite element analysis to characterize and improve the solder's fatigue life, finding that reducing the encapsulant's CTE significantly extended its durability.

Overcoming element erosion limitations within Lagrangian finite element codes

This paper focuses on overcoming the limitations of Lagrangian finite element codes. It proposes a new method to deal with element erosion, which is a key issue when modeling large deformations from events like high-velocity impacts. The research demonstrates the effectiveness of this FEA method by comparing simulation results with experimental data.

Offset Impact Behaviour of Bumper Beam-Longitudinal Systems: Numerical Simulations

This paper presents numerical simulations of bumper beam-longitudinal systems under offset impact loading, demonstrating how Finite Element Analysis (FEA) is used to accurately model and predict crash behavior. The research, which utilized the non-linear finite element code LS-DYNA, validates the effectiveness of FEM in simulating crash events and evaluating energy absorption.

Lower Extremity Finite Element Model for Crash Simulation

Dale A. Schauer, Scott A. Perfect

This technical paper presents a finite element model of the human lower extremity to simulate crash events and study injury mechanisms. The model, which incorporates detailed bone and soft tissue geometry, utilizes a non-linear large deformation finite element code to analyze stress and strain during vehicle collisions, highlighting the critical role of Finite Element Analysis (FEA) in crash simulation and occupant safety research.
