The paper describes an explicit coupling procedure for efficient consolidation analysis. Each time step is divided into a flow step followed by a drained mechanical step. The flow step keeps the total mean stress increment fixed and solves a diffusion problem based on piecewise constant pressure data. The procedure can be added to purely mechanical finite element codes and does not require a fully coupled element type. Details on discretization and implementation are provided as well as results of numerical tests.

使用分段恒压的显式耦合固结分析

本文介绍了用于有效合并分析的显式耦合过程。每个时间步骤都分为流动步骤，然后是排空的机械步骤。流动步骤使总平均应力增量保持固定，并基于分段恒定压力数据解决扩散问题。该过程可以添加到纯粹的机械有限元代码中，并且不需要完全耦合的元素类型。提供了离散化和实现的详细信息以及数值测试的结果。
