To obtain 3D relations, some simplifying assumptions are made. In the case of concrete, it is assumed that the Poisson ratio does not change with time. In the cas

Zur Geschichte des Berufs der Erzieherin,rials, particularly polymers, have temperature dependent constitutive relations. The mechanisms responsible for these thermal effects have micro-structural origin and are, consequently, complex. In this chapter we present a brief description on temperature effects on the linear viscoelasticity behav

Concrete is a material that may be used as an example: from the moment of casting (taken usually as age zero) it begins to increase its strength and to decrease its deformability. In the case of polymers both physical (reversible) and chemical (irreversible)

Geometrical nonlinearity corresponds to situations of large deformations (large displacements and/or large strain). Both effects can appear combined in some problems (e.g. polymers, biomechanics). Alternative nonlinear or quasi-lin

In this chapter, we present an incremental viscoelastic finite element formulation for problems with geometrical nonlinearity characterized by large displacements and rotations with small strains. The formulation is based on a total Lagrangian kinematic description. We begin with a brief pres

This formulation can only be derived for certain classes of problems and hence, is not as widely applicable as the finite element method. However, when applicable, it often results in numerical methods th
