| dc.description.abstract | In this work, I develop a 1D finite-difference formulation that is capable of simulating non-welded contact boundary conditions in anelastic media. I include, in the linear-slip boundary conditions for non-welded contact, the memory variables that are obtained as a result of considering a generalized Maxwell rheology. Then I proceed to obtain a heterogeneous formulation which is a result of the introduction of a fictitious points scheme for the boundary conditions. In other words I obtain a generalized homogeneous formulation. I solve the resulting system of equations and substitute the amplitudes obtained into the equation of motion. I analyze the numerical results obtained and compare these with an analytical solution and two other anelastic formulations for the welded contact case. I examine different scenarios such as anelastic-anelastic and elastic-anelastic wave propagation in welded and non-welded contact by looking at the transmitted and reflected pulse in welded as well as non-welded contact. | en_US |
