Physical and Geometric Non-Linear Analysys via FEM of Truss Structures

This book intends to develop mathematical modeling and illustrates the code program developed to analyze trusses under load considering physical and geometric non-linearities. It is performed the characterization of the structure, its peculiarities and the description of the calculation premises. Physical and geometric non-linearities are described and pointed out the elastoplastic behavior on the structure. The computation aspects and its implementation are discussed and it is presented some examples illustrating code programs.
