LS-DYNA is the first commercial code to support IGA through the implementation of generalized elements and then keywords supporting non-uniform rational B-splines (NURBS). Many of the standard FEA capabilities, such as contact, spot-weld models, anisotropic constitutive laws, or frequency domain analysis, are readily available in LS …

Hyperelastic materials are defined by a constitutive model which derives the stress–strain relationship from a strain energy density function. They are highly elastic materials so that their deformations can be recovered when subjected to very large strains. For many materials, linear elastic models do not accurately describe the observed ...

1 Introduction to LS-DYNA LS-DYNA is a program with capabilities to solve multi-physics problems such as solid mechanics, heat transfer, and fluid dynamics. Moreover, these problems could be solved either as separated phenomena or as couple physics. This handout is intended to assist the new LS-DYNA user get started. 2 Running LS-DYNA

Composite tubes displaying Type I crush morphology have been successfully modeled by progressive damage models. Mamalis et al used MAT54 with LS-DYNA® to simulate carbon woven fabric/epoxy square tubes [11] and composite face sheets in composite tubes of sandwiched wall construction with a foam core [12]. By adjusting the TFAIL, a time step …

2 tube showing the formation of the debris wedge after approximately 5 mm of applied displacement and (b) schematic showing the debris wedge and fracture mechanisms in a section of the tube wall. Finite Element Model The LS-DYNA simulations consisted of 4 main components: a drop weight, a tube, a debris wedge and a rigid plate as shown in …

In the Finite Element Analysis (FEA), aluminum alloy AA6061-T4 is defined as piecewise linear plasticity material model 24 in LS-DYNA. Metal-FRP hybrid tubes were modeled by two layers of shell elements, and the material of inner layer is aluminum with a thickness of 1.2 mm, that of outer layer is GFRP with a thickness of 1.2 mm.

The composite tube was modeled using shell elements. The tube was joined to the drop weight through constrained nodes. An initial velocity of 7.1 m/s was assigned to the drop weight and theConclusions. The constitutive responses of a composite damage material model, MAT58, in LS-DYNA were investigated using a single element test.

2 The Discrete-Element Method in LS-DYNA In LS-DYNA, the DEM is realized using rigid spherical particles, while interactions with other rigid or deformable structures are accomplished using penalty-based contact algorithms. Note that the DEM computes the motion of each spherical particle using Newton's law of motion and thus, each particle
