However, the stresses are singular both at the edges of contact and at the sharp corners. This paper considers the Dugdale model in fracture mechanics, and smoothness of the wedge profile, which suppresses these stress singularities. The approach avoids the self-consistent calculations for the real material potential. Complete analyses are given for the contact pressure distribution, the load-contact-area relationship and the variation of the air gap with the load. The results are compared with those in molecular dynamics simulations, which show more refined features of surface adhesion mechanisms. This work on the truncated wedge geometry is supplemental to the work of Maugis on the adhesion of spheres and the work of Johnson on the adhesion of cylinders. [References: 23] 收起
