ANISOTROPIC PLATES LEKHNITSKII PDF

Hwu, C. September 1, September ; 57 3 : — In the case when an anisotropic plate contains a triangular, oval, or square opening, the only solution available in the literature is an approximate solution for orthotropic plates with openings, which was obtained by Lekhnitskii using the complex variable formulation. Solutions for any kind of anisotropic plates with various openings are presented in this paper by applying the Stroh formalism and using the technique of conformal mapping. Unlike the former results, which have different orders of approximation for different openings, the solutions presented here have only one simple unified expression for various openings such as the ellipse, circle, crack, triangle, oval, and square.

Anisotropic Elastic Plates find wide applications as structural elements in modern technology. The plates are considered to be subjected to not only inplane loads but also transverse loads. Plane problems, plate bending problems as well as stretching-bending coupling problems are all treated in this book. In addition to the introduction of the theory of anisotropic elasticity that includes two complex variable methods - Lekhnitiskii formalism and Stroh formalism- several important subjects are also discussed such as wedges, interfaces, cracks, holes, inclusions, contact problems, piezoelectric materials, thermal stresses and boundary element analysis. Anisotropic Elastic Plates also collects over one hundred problems and solutions. This book is a useful resource for engineers and researchers in composite materials.
