The study of the construction of a micro-scale rupture parameter from the perspective of rock stress and strain is a frontier in geoscience. The strain energy density (U) can quantitatively characterize the probability of internal micro-scale ruptures in different types of rock. Based on this. in this paper. https://www.diwalishare.com/product-category/school-supplies-office-organization-document-organization-and-protection-sheet-protectors-office-and-school-office/
