RT Journal Article ID 102a14a31e0f8e19 A1 Dureisseix, David A1 Ladeveze, Pierre A1 Neron, David A1 Schrefler, Bernhard T1 A Multi-Time-Scale Strategy for Multiphysics Problems: Application to Poroelasticity JF International Journal for Multiscale Computational Engineering JO JMC YR 2003 FD 2003-11-01 VO 1 IS 4 OP 14 AB Usually, multiphysics phenomena and coupled-field problems lead to computationally intensive structural analysis. Strategies to keep these problems computationally affordable are of special interest. For coupled fluid-structure problems, for instance, partitioned procedures and staggered algorithms are often preferable to direct analysis.
In a previous article, a new strategy derived from the LArge Time INcrement (LATIN) method was described. This strategy was applied to the consolidation of saturated porous soils, which is a highly coupled fluid-solid problem. The feasibility of the method and the comparison of its performance with that of a standard partitioning scheme (the so-called ISPP method) was presented.
Here, we go one step further and use the LATIN method to take into account the different time scales that usually arise from the different physics. We propose a multi-time-scale strategy, which improves the existing method. PB Begell House LK https://www.dl.begellhouse.com/journals/61fd1b191cf7e96f,7910ba8e078c1422,102a14a31e0f8e19.html
