Contact of faces of a rectilinear crack under complex loading and various contact conditions

Linear interface crack under harmonic shear: Effects of crack's faces closure and friction

“…As a conclusion, it shall be added that the proposed approach may be extended to three-dimensional fracture mechanics problems for cracked materials under arbitrary dynamic loading, and the special attention shall be paid to the coupling oscillation singularities in the vicinity of the crack's front [2,5,49,50].…”

Effects of crack closure and friction for linear crack under normal impact

“…The contact constraints (22) ensure that there is no interpenetration of the opposite crack faces; the normal component of the contact force is unilateral and it is absent for any non-zero opening of the crack. Note that, due to the contact interaction the traction vector at the crack faces is the superposition of the initial traction caused by the incident load and the contact force.…”

Contact Problems for Interface Cracks Under Harmonic Shear Loading

“…It shall be specifically noted that the opposite faces of the existing cracks almost always interact with each other under deformation, significantly changing the solution near the crack [13][14][15][16][17][18][19][20][21][22][23]. The nature of the dynamic contact interaction between opposite crack faces is very complex.…”
