Optimization with Non-Homogeneous Failure Criteria (Tsai Wu) Criteria (Tsai-Wu) INTRODUCTION: The minimization of a failure criterion (i.e. Tsai-Hill) 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 factor instead of minimizing the failure index is appropriate

Optimization with Non-Homogeneous Failure Criteria (Tsai Wu) Criteria (Tsai-Wu) INTRODUCTION: The failure of composite structures is not perfectly understood 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)

Optimization with Non-Homogeneous Failure Criteria (Tsai Wu) Criteria (Tsai-Wu) INTRODUCTION: Equation above is the Tsai-Wu criterion Counter intuitive to minimize the failure index when designing a laminate under this constraint; results would be load-dependent Maximization of the safety factor instead yields load- independent results

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
