| Abstract: | This work is making a study of the mixed mode inclined crack extension of solidsby compressive loading under considering the effect of crack surface friction. Thepresent is using Hilbert's boundary value problem obtain an exact solution of thestress intensity factor and the initial angle of crack growth. The present theoreticalresults will be shown to agree well with the experiment by Hoek and Bieniawski.Namely, the crack path under uniaxial compression is towards the direction of loa-ding. Another, the present analysis results will be shown to agree well with the direc-tion of fault extension for the July. 27, 1976, Tangshan earthquake, China. |
