Tribol. 2006;128(4):828-840. doi:10.1115/1.2345407 Figure Legend: (a) Overview of the finite element model used to validate the numerical computation of adhesive forces acting on the test mass. The half-plane-sphere contact has been analyzed, assuming axial symmetry. (b) Detail of the finite element model near the contact region.
