Effect of friction of the crack faces for a linear crack under an oblique harmonic loading

This paper concerns fracture dynamics problems for elastic cracked solids with allowance for the crack faces contact interaction. The problem for a linear crack under an oblique time-harmonic wave is solved by the method of boundary integral equations. The effect of friction, governed by the Coulomb friction law, is incorporated into the analysis. The results are obtained for various values of the angle of the wave incidence, the wave frequency and the friction coefficient. They are compared with those obtained without allowance for the crack faces contact interaction.
