DEVICE FOR DETERMINATION OF CRACKING, PROGRAM FOR DETERMINATION OF CRACKING AND ITS METHOD Russian patent published in 2020 - IPC G01N3/28 G01N19/08 

FIELD: test equipment.

SUBSTANCE: invention is related to testing equipment. Device 1 of determination of cracking is equipped with unit 22 of formation of base value of molding limit, which based on information on basic value of molding limit forms basic value of molding limit for basic size of element, which is size of element used as base of reference, shaping limit target value forming unit 23, which uses the tensile strength of the steel material to change the molding base basic value, predicting the molding element size value by the element size and forming the molding limit target value, analysis execution unit 24, which performs analysis of change of shape using input information and which provides information on change of shape, including deformation of each of the elements, main deformation determining unit 25, which determines maximum main deformation and minimum main deformation of each of elements, included in the shape change information, and the crack determination unit 26, which, based on the determined maximum main deformation and the minimum principal deformation of each of the elements and the target molding value, determines whether each element of the analysis model is cracked.

EFFECT: possibility of properly predicting cracking in accordance with the size of an element from steel material, including also from super-high strength steel, which ultimate tensile strength is 980 MPa or more.
