Static nonlinear third-order elastic moduli inversion and numerical simulation of their effects on wellbore stress distribution

The dataset contains experimental data from rocks subjected to both uniaxial and hydrostatic compressive tests, matlab scripts for processing the data and performing third-order elastic (TOE) moduli inversion, and finite element model files, which use the inverted elastic moduli to compute the stress distribution around the wellbore in both linear elastic and nonlinear TOE cases.本数据集涵盖经受单轴压缩及静水压缩试验的岩石实验数据、用于处理实验数据并开展三阶弹性（TOE）模量反演的MATLAB脚本，以及采用反演所得弹性模量，分别在线弹性与非线性三阶弹性工况下计算井筒周围应力分布的有限元模型文件。
