【Abstract】 Microstructural characteristics of quasi-brittle material’s damage and fracture as concrete is analyzed in this paper. Based on the stress and strain curve of concrete compress examination, a formula with power and index is established, in which the characteristics of compress examination curve are expressed. The method to calculate an index of the equation is presented, and some discussions are also given in the paper.\;更多还原
