Hill failure analysis (2D)

Failure Index

The expression of the Hill failure criterion is:

Where F is the failure index and:

For the cross term :

X = X**T if σ1 and σ2 are of the same sign.

X = X**C if σ1 and σ2 are of different signs.

For other variable definitions see Laminate failure analysis nomenclature.

Margin of Safety

The margin of safety calculated as a percentage, MS, is based on a quadratic equation, and can be reduced to:

Strength Ratio

The strength ratio, SR, is:
