Abstract : The thesis begins with a comprehensive formulation of continuum-based finite element theory. The theoretical portion concludes with the details of both spatial and temporal discretization, including a discussion of nonlinearity. This study is to understand the effects of nonlinear behavior of structures using a finite element method. The nonlinear behavior equations are derived from equations of motion and constitutive equations. The basic theory is the principle of virtual work. In particular, large displacement problems and visco-elastic problems remain a challenging engineering problems today. The viscoelastic problems depend on the relaxation function which is the source of material nonlinearities. Keywords: Viscoelastic structures problems.
