Ebook: Finite Element Structural Analysis: New Concepts

Finite Element Structural Analysis: New Concepts introduces a novel concept for accurately assessing the solution accuracy of the powerful and versatile finite element structural simulation technology. This has the potential of significantly improving the process of developing related new analysis codes and modification of existing ones, so as to generate reliable solution bounds. This text covers finite element developments pertaining to assumed displacements distribution, corrective distribution superimposed on assumed displacement distribution, and assumed stress distribution within an element. It addresses a wide array of elements including plane plate (triangular and quadrilateral), as well as solid elements (tetrahedron, prismatic pentahedron, and rectangular hexahedron). Each element's stiffness and its thermal and mass matrices are derived in careful detail. Highly recommended for graduate and senior level undergraduate courses in engineering mechanics (particularly those related to aeronautics and associated disciplines), the text will also provide invaluable guidance for practicing engineers in accurate modeling and simulation of problems encountered in industry.
