This reference explains hybrid-Trefftz finite element method (FEM). Readers are introduced to the basic concepts and general element formulations of the method. The book consists of two major parts: Part I Trefftz FEM and Part II fundamental solution based FEM. In the first part, Chapter 1 gives an introduction and overview of the hybrid-Trefftz FEM. Followed by topics on non-homogeneous parabolic problems, thermal analysis of composites, and heat conduction in nonlinear functionally graded materials. A brief summary of the fundamental solution based-FEM is also presented followed by a discussion on axisymmetric potential problems and the rotordynamic response of tapered composites. The book is rounded by chapters which cover the n-sided polygonal hybrid finite elements and analysis of piezoelectric resources. It includes solutions to problems in the numerical analysis of different material types and solutions to some problems encountered in civil engineering (seepage, heat transfer, etc).
This reference is suitable for Scholars at graduate and postgraduate levels in mathematics, civil engineering and materials science. Professionals involved in developing analytical tools for materials and construction testing can also benefit from the methods presented in the book.
