Alternative time marching process for BEM and FEM viscoelastic analysis

Based on the weighted residual technique, both Finite Element and Boundary Element alternative procedures for viscoelastic analysis are proposed. After imposing the space approximations, applying the kinematical relations for material and strain velocities at the approximation level, the time integration is carried out using appropriate operators. The Kelvin-Voigt viscoelastic model is implemented in order to validatetheide a. TheNe wmark time integral scheme is applied to the Finite Element procedure whiletheHoubolt schemeis applied to theBoundary Elements, allowing theconside ration of dynamic analysis in futureworks.
