摘要翻译:
在多相固-液体系中施加应力往往会导致形貌不稳定性。本文提出了两种不同孔隙率的多孔材料在法向压缩应力作用下界面粗糙化不稳定性的固-固相变模型。这种不稳定性是由界面自由能密度的有限跳变触发的,它导致与压实主方向对准的指状结构的形成。该模型解释了柱长石的粗糙化--与沉积岩压实有关的不规则界面,这些界面围绕垂直于压实主方向的平面波动。

英文摘要:
The application of stress to multiphase solid-liquid systems often results in morphological instabilities. Here we propose a solid-solid phase transformation model for roughening instability in the interface between two porous materials with different porosities under normal compression stresses. This instability is triggered by a finite jump in the free energy density across the interface, and it leads to the formation of finger-like structures aligned with the principal direction of compaction. The model is proposed as an explanation for the roughening of stylolites - irregular interfaces associated with the compaction of sedimentary rocks that fluctuate about a plane perpendicular to the principal direction of compaction.
