摘要

我们简要比较了两种流行模型的结构，以模拟多孔力学和化学力学，其中液相在固相中传输。乘法变形分解已被用于建模塑性和热膨胀中的永久非弹性形状变化。然而，能量分解为孔隙力学和化学力学问题提供了更透明的结构和优势，例如耦合到相场断裂。

Deformation Decomposition versus Energy Decomposition for Chemo- and Poro- Mechanics

We briefly compare the structure of two popular models to model poro- and chemo- mechanics wherein a fluid phase is transported within a solid phase. The multiplicative deformation decomposition has been used to model permanent inelastic shape change in plasticity and thermal expansion. However, the energetic decomposition provides a more transparent structure and advantages, such as to couple to phase-field fracture, for problems of poro- and chemo- mechanics.
