Ferrocoke strength measuring and calculating method

The invention provides a method for measuring and calculating ferrocoke strength. According to the method, slice collection and pretreatment, feature extraction, vectorization model construction, finite element calculation and other operations are carried out on a ferrocoke sample, a weak region of a ferrocoke tissue is focused, a real stress grid structure is restored, the stress distribution condition of the ferrocoke sample under an extreme condition is simulated, the mechanical property features of the ferrocoke are described from a microcosmic angle, and the mechanical property characteristics of the ferrocoke are analyzed. And evaluating the stress enrichment state of the whole sample. In the modeling process, a grid construction method based on a vector graph is applied, details can be restored while the number of model surfaces is reduced, and the accuracy of a result is ensured; besides, the microscopic strength performance index of the sample can be obtained after the finite element model is solved,
