Core ply material failure analysis

Using the core ply material, this software computes two failure index result sets, two margin of safety result sets, and two strength ratio result sets: one for the shear in plane 13 and one for the shear in plane 23.

Core results replace the in-plane ply results in advanced post reporting of laminate results.

Failure Index

Failure indices, F, are computed as follows:

K(t) is the strength correction factor that can be either constant or a function of the ply thickness, t.

Margin of Safety

Margins of safety, MS, are computed as follows:

where FS is the specified safety factor.

Strength Ratio

The strength ratio, SR, is:
