Retraction Note: Analysis of fractured soft rock characteristics in
The Authors have retracted this Article. After the publication of the Article, the Authors discovered that their TAW-2000 rock testing machine had developed a malfunction. The machine was used in most of the experiments and the Authors cannot be certain at which point the machine failed. The Authors therefore no longer have confidence in the data.

Simple formula learned via machine learning for creep rupture life
Machine learning (ML) has been employed to build surrogate models for creep rupture life; however, the commonly used algorithms are often black-box due to the pursuit of high accuracy. Here, we first show that multiple linear regression (MLR) can result in models or formulae with much higher accuracy than those based on typical black-box methods.

Study on the Evolution of Rock Fracture under True Triaxial
Based on the results of the CT scans in which the fracture dip angle within the rock is approximately parallel to the σ 2 direction under different true triaxial paths, the intermediate principal stress plays a vital role in rock rupture. Combined with experimental and theoretical analyses, the rationality of this effect was verified.
