Optimization with Non-Homogeneous Failure riteria (Tsai u) Criteria (Tsai-Wu) INTRODUCTION: N O UC ON: The minimization of a failure criterion (i.e. Tsai-Hill) ay be an objective in designing composite laminates may be an objective in designing composite laminates This procedure is suitable for homogeneous criterion, but not non-homogeneous criterion For non-homogeneous criterion, maximizing a safety g, g y factor instead of minimizing the failure index is appropriate

Optimization with Non-Homogeneous Failure riteria (Tsai u) Criteria (Tsai-Wu) INTRODUCTION: N O UC ON: The failure of composite structures is not perfectly nderstood though numerous failure models have been understood, though numerous failure models have been proposed Tsai-Hill, Tsai-Wu and Hoffman’s variation accounts for interactions between different stress components Tsai-Hill criterion is observed to be homogeneous; Tsai-Wu is inhomogeneous (presence of linear terms)
