| Abstract: | It is important and necessary for a building to analyze the damage of engineering structures, to calculate the service life, and to study the dense-toughness and damage mechanism of the materials carefully. And then, the research will have a wider using and developing future. In the case of the limited level density of the material surface energy, the fracture stress and the calculation formula of the engineering damage were studied. |
| Keywords: | effective stress damage factor damage moduli surface energy density fracture stress |
