Layered Slab (LS-DYNA)

When creating a model for analysis in LS-DYNA it is useful to be able to define a composite shell. This is defined in terms of layers of different materials.

Definition​

The composite shell is defined from the bottom up in layers. Each layer is defined by an analysis material, a thickness and an optional angle for orthotropic materials. The total thickness of the shell is determined from the sum of the layer thicknesses.

Syntax​

The description of  hollow slab profile is

(unit) L (mat thick angle) ...

where

  • unit – the units defining the profile
  • L – layered slab
  • thick – the layer thickness
  • angle – the angle of the layer for an orthotropic material

The material, thickness and angle are repeated for each layer.
