能源地下储存中地质材料开裂过程的相场模型与验证分析
Phase-field Modeling of Fracture in Geomaterials for Subsurface Energy Storage
摘要
Abstract
In this contribution,the development of a continuum phase-field model of brittle fracture for poroelastic solids is presented.The phase-field approach treats the discontinuity at the discrete lower-dimensional crack interface in a continuous diffusive setting.The system of equations is treated numerically by a monolithically coupled Newton-Raphson iterative-incremental solution strategy to be a scientific open-source finite element software OpenGeoSys.This contribution presents the governing equations along with details of said numerical implementation together with verification examples and perspectives for model application.关键词
