Abstract Failure tests on marble during unloading confining-pressure under constant axial stress and simulations with the particle flow code were performed.The influence mechanism of the unloading rate of the confining pressure, initial unloading stress, and Shower Cap confining pressure on the failure characteristics of, and crack propagation in,
This article aims to introduce a unique hypersoft time-based matrix model that organizes and classifies higher-dimensional information scattered in numerous forms and vague appearances varying on specific time levels.Classical matrices as rank-2 tensors single-handedly relate equations and variables across rows and columns are a limited approach to
