In the standard treatment of consolidation equation (see, for instance, Lewis and Schrefler 1998), the acceleration terms are generally omitted a priori. However, as explained above, there is no disadvantage in writing the full dynamic formulation for solving such a problem. The procedure simply reduces the multiplier of the mass matrix M to a negligible value without influencing in any way the numerical stability, provided, of course, that an implicit integration scheme is used.
