Calculating injection/production pore pressure-induced stress around re-fracturing wells with the preparation of FEM,three-dimensional distribution of induced stress is given through 3Dsurfer software.

The induced stress of initial damage zone results in the redistribution of surrounding rock stress when the micro-crack closes after hydraulic fracture.

Quantitative analysis and simulation are also done for this induced stress field.

Since the successive layers have facing surfaces with mated topography, it is considered that the seperating of the layer from the reaction front should relate to the diffusion-induced stresses developing within the separating of the layer during solid state reactions.

Considered that little has been known in a detailed way of the mechanisms of diffusion-induced stresses, the relationship of atomic diffusion and stresses in solids will be elucidated and the concepts of creep-induced diffusion and diffusion-induced stresses are clarified in this paper.

Rational formula of border column punching is also suggested in consideration of the stress diffusion.

Critical edge pressure of soft clay foundation considering closure effect and stress dispersion of crust;

Theory of composite foundation considering stress dispersion and its application in engineering

Investigation of the influences of various geometric parameters on the stress distribution showed that the most important factors influencing the stress dispersion are the web thickness and the inertia moment of the rail,while the inertia moment of the top flange has only minor influence.
