| Abstract: | We solve a fracture-mechanics problem for a cracked material under polyharmonic loading (waves of various lengths propagating
through an elastic material). The frictional contact interaction of the finite crack edges in a plane is analyzed for the
case of normal incidence of two harmonic shear waves with different frequencies. The forces of contact interaction and displacement
discontinuity are determined. The effect of the wave frequency on the stress intensity factor for different normalized wave
numbers is examined |
