The objective of this paper is to present a numerical algorithm for calculating hyperelastic constitutive equations characterizing the thermomechanical response of elastically isotropic elastic-viscoplastic materials. The algorithm is developed within the context of an alternative formulation of pla

โฆ Synopsis
Linearized equations describing small motions superimposed on finitely deformed equilibrium configurations of elastic networks are derived. The theory is based on the so-called membrane model in which the fibres of the network are assumed to be continuously distributed to form a surface. A consistent linearization method is used to obtain equations of motion valid for arbitrary underlying equilibrium deformations. Modal analysis is performed for a sector of a one-parameter family of hyperbolic paraboloids with non-linearly elastic fibres, and the effect of geometric and material non-linearity on the frequency response of the network is quantified.
