Elastodynamic Problem for Two Penny-Shaped Cracks: The Effect of Cracks’ Closure
by Menshykov, Oleksandr V.; Guz, Igor A.
The paper is devoted to the solution of the three-dimensional elastodynamic problem for linearly elastic, homogeneous and isotropic solid with two penny-shaped in-plane cracks under normally incident harmonic tension-compression wave with allowance for the contact interaction of crack faces. The effect of the distance between cracks on the stress intensity factor (opening mode) is studied for different wave numbers. The results are compared with those obtained neglecting the cracks’ closure.
