A new discrete numerical method for rock dynamics

The first numerical computation theory that adopts the parallel world hypothesis. For the first time, a four-dimensional space discrete model, 4D-LSM, is proposed by introducing the concept of extra dimension of space into the solid mechanics model. Based on the application of rock engineering, the problem of large deformation and small deformation is successfully integrated by introducing the concept of extra dimension of space in modern physics, at the same time, it avoids rigid-body rotation angle separation operation in traditional continuous medium method and step-by-step accumulation operation in traditional discrete method, and provides a new numerical calculation theory for solving rock mechanics and engineering problems.
