FRACTURE PREDICTING METHOD, SOFTWARE, RECORDING MEDIUM AND ARITHMETIC PROCESSING DEVICE Russian patent published in 2019 - IPC G01N3/28 

FIELD: computer equipment.

SUBSTANCE: invention relates to the fractures prediction method, software, recording medium and the arithmetic processing device for the fracture region prediction, when the molding analysis is performed by means of the finite elements method. Essence: performing the molding analysis first stage using the finite elements method in each of the case, in which the metal sheet is divided based on the mesh cells first size, and the case, in which the metal sheet is divided on the basis of the mesh cells second size, which is larger than the mesh cells first size, the maximum main mechanical stress obtaining second stage for each mesh in each of the cases of the mesh cells first size and the case of the mesh cells second size, and the third stage of obtaining the difference value between the maximum main mechanical stress in the case of the mesh cells first size and the maximum main mechanical stress in the case of the mesh cells second size in of the component each section, and the section separation in the case of the mesh cells first size, which corresponds to the section, wherein the difference value is greater than the predetermined value, as the fracture region.

EFFECT: increase in the prediction reliability.
