Along with the development of computing science, rock core discing numerical simulation more and more being at a premium.
The main cause of rock mass stability is destroy stress being larger than resistance, the former is resulted from stress environment, the latter depends on the strength parameters of material strength.

PWBs consist of copper foil and insulation layers, which are composite materials composed of a glass cloth and epoxy resin.
Because materials with different physical properties are processed simultaneously, the processing phenomena become extremely complex.

This yield criterion applies well to ductile materials, such as aluminum.
The von Mises stress is used to predict yielding of materials under any loading condition from results of simple uniaxial tensile tests.
