The finite element method (FEM), or finite element analysis (FEA), is a computational technique used to obtain approximate solutions of boundary value problems in engineering. Boundary value problems are also called field problems. The field is the domain of interest . The second edition of An Introduction to Nonlinear Finite Element Analysis has the same objective as the first edition, namely, to facilitate an easy and thorough understanding of the details that are involved in the theoretical formulation, finite element model development, and solutions of nonlinear problems. The book offers an easy-to-understand treatment of the subject of nonlinear finite Cited by:

At the last step, the present finite element model is used for the large deformation analysis of tapered nanowires. The tapered nanowires with the sinusoidal distributed external loads are considered to show the capability of the present model to analyze nanowires with non-uniform cross sections and arbitrary by: 3.
