Development of Guardrail End Treatment System using LS-DYNA

LS-DYNA® Best-Practices: Networking, MPI and Parallel File System Effect on LS-DYNA Performance

From concept to engineering, and from design to test and manufacturing, the automotive industry relies on powerful virtual development solutions. CFD and crash simulations are performed in an effort to secure quality and accelerate the development process. The recent trends in cluster environments, such as multi-core CPUs, GPUs, cluster file systems and new interconnect speeds and offloading ca...

Simulating laminated composites using LS - DYNA material model

A wide range of composite material forms are finding use in today’s aerospace, automotive, and other transportation industry segments. The Boeing 787 commercial airliner, unveiled in 2007, features over 50% carbon fiber composites by structural weight, while the entire structure of the Lamborghini Sesto Elemento supercar, unveiled in 2011, is made exclusively from carbon fiber composites [1-2]....

Development of a New End Treatment for Steel-Backed Timber Guardrail: Phase I Conceptual Design

The purpose of this research is to determine the feasibility of developing a new aesthetic, crashworthy terminal for the steel-backed timber (SBT) guardrail system for use by the National Park Service and others along park roads and scenic highways. Two conceptual designs, a flared non-energy absorbing concept and a parallel energy absorbing concept, were developed using the same materials that...

Development of Guidelines for Deformable and Rigid Switch in Ls-dyna Simulation

Pre-processor Software for Calibration of LS-DYNA Material Models

LS-DYNA contains a wealth of material models that allow for the simulation of transient phenomena. These models are often quite complex and difficult to calibrate. We present CAE Modeler, a generalized pre-processor software used to convert material property data into material parameters for different material models used in CAE. In this paper, CAE Modeler is used to streamline the conversion o...
