Predicition of Laminate Failure using Classical Laminate Theory (CLT)

The Tsai-Hill criterion is a quadratic, interactive stress-based criterion that identifies failure, but does not distinguish between different modes of failure.

Failure occurs whenever the following condition is satisfied.

The coefficients Sij of the Tsai-Hill criterion are computed as follows:

S⁺₁₁ = Value of σ₁₁ at longitudinal tensile failure

S^-₁₁ = Value of σ₁₁ at longitudinal compressive failure

S⁺₂₂= Value of σ₂₂ at transverse tensile failure

S^-₂₂ = Value of σ₂₂ at transverse compressive failure

S₁₂ = Absolute value of σ₁₂ at longitudinal shear failure
