Topology Optimization in Crashworthiness Design

This study presents a topology optimization method for crashworthiness design, focusing on material redistribution using internal energy density (IED) in explicit finite element analysis. The approach accommodates nonlinearities like contact-impact and plasticity, refining material distribution to enhance structural efficiency under crash loads.

A design optimization approach of vehicle hood for pedestrian protection

This study focuses on developing and validating a finite element model of a headform impactor for use in pedestrian head injury risk assessment. It then uses this model in an optimization problem to minimize underhood clearance while meeting safety requirements by adjusting parametric variables like connecting spool geometry and panel thicknesses.

Response Surface and Sensitivity-Based Optimization in LS-OPT: A Benchmark Study

This study benchmarks LS-OPT’s response surface and sensitivity-based optimization approach for parametric modeling, highlighting its utility in shape optimization. By constructing local linear approximations and applying an adaptive domain reduction scheme, the method achieves robust convergence on challenging design problems.

Human Response to High-Rate Loading

This study utilizes advanced parametric modeling and shape optimization techniques to develop a probabilistic finite element model of the tibia and talus. By integrating statistical shape analysis with robust mesh correspondence methods, the research captures anatomical variability and predicts fracture risk under high-rate loading conditions.
