ISBN-13: 9780195074475

Anisotropic Elasticity deals for the 1st time a complete survey of the research of anisotropic fabrics which could have as much as twenty-one elastic constants. concentrating on the mathematically dependent and technically robust Stroh formalism as a method to realizing the topic, the writer tackles a vast variety of key subject matters, together with antiplane deformations, Green's capabilities, rigidity singularities in composite fabrics, elliptic inclusions, cracks, thermo-elasticity, and piezoelectric fabrics, between many others. good written, theoretically rigorous, and essentially orientated, the publication may be welcomed through scholars and researchers alike.
