TsaiWuFailureTheory
Calculates the Tsai-Wu Ply Failure Index.
Inputs
- elems
- An element entity table.
- parts
- A part entity table.
- props
- A property entity table.
- xt
- A material scalar table.
- xc
- A material scalar table.
- yt
- A material scalar table.
- yc
- A material scalar table.
- s
- A material scalar table.
- f12
- A material scalar table.
- layer_idx
- A layer index.
- tensor
- An elemental tensor value table.
Outputs
- answer
- An elemental scalar value table.
Comments
- xt: Allowable tensile stress in ply material direction 1.
- xc: Allowable compressive stress in ply material direction 1.
- yt: Allowable tensile stress in ply material direction 2.
- yc: Allowable compressive stress in ply material direction 2.
- s: Allowable in-plane shear stress.
- f12: Tsai-Wu experimental factor.
- tensor: Stress tensor table.
- The calculation of Tsai-Wu Failure Theory is for shell elements only, and applies to 2D tensors relative to the ply material system as described in the OptiStruct documentation for “Composite Laminates”.
- layer_idx = layer index for the chosen data type, assigned by the HyperWorks application, and defaults to the value “@current_slice_index”. @current_slice_index represents the layer index for the chosen datatype.
