A Simulation Framework for Battery Cell Impact Safety Modeling Using LS-DYNA

LS-DYNA Impact Simulation of Composite Sandwich Structures with Balsa Wood Core

The impact damage response of balsa core sandwich composite plates with S2-glass/ epoxy reinforced facesheets is evaluated by impacting them with a spherical steel projectile at single impact locations. The impact damage can significantly reduce the structural integrity and load bearing capacity of a composite structure. Under high velocity impact loading, laminated composites experience signif...

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]....

Modeling Tire Blow-out in Roadside Hardware Simulations Using Ls-dyna

Often when vehicles interact with roadside hardware like guardrails, bridge rails and curbs, the interaction between the roadside hardware and the tire causes the tire to lose its air seal and "blow-out". Once the seal between the rim and rubber tire is lost, the tire deflates. The behavior of the deflated tire is much different than the behavior of an inflated tire such that when this behavior...
