چکیده

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]. An attractive benefit of using composite materials is the ability of composite crush structures to dissipate large amounts of energy which has been shown to exceed that of their metallic counterparts [3]. If properly engineered, implementing composite crash subcomponents in aircraft and cars, such as collapsible floor stanchions and frontal crush beams, can substantially increase crashworthiness and vehicle safety. Such composite crash components are featured in both the Boeing 787 and the Lamborghini Sesto Elemento.

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...

Implementation and Validation of the Johnson-Holmquist Ceramic Material Model i

Ceramic materials are commonly used in protective armour applications and may be subject to high-energy ballistic impacts in these situations. Under simple loading conditions, ceramics may be regarded as elastic-brittle materials. However, when considering ballistic impacts, the post-yield response of the ceramic becomes significant. One of the most widely used constitutive models for simulatin...

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...

Finite Element Modeling of Multilayer Orthogonal Auxetic Composites under Low-Velocity Impact

The multilayer orthogonal auxetic composites have been previously developed and tested to prove that they own excellent energy absorption and impact protection characteristics in a specific strain range under low-velocity impact. In this study, a three dimensional finite element (FE) model in ANSYS LS-DYNA was established to simulate the mechanical behavior of auxetic composites under low-veloc...

BACKGROUND In the state of the art finite element AHBMs for car crash analysis in the LS-DYNA software material named *MAT_MUSCLE (*MAT_156) is used for active muscles modeling. It has three elements in parallel configuration, which has several major drawbacks: restraint approximation of the physical reality, complicated parameterization and absence of the integrated activation dynamics. This s...
