1108 表面エネルギーの変化を考慮した凝着理論  [in Japanese] Adhesion theory considering a variation of surface energy  [in Japanese]

The adhesion contact analysis using the theory of elasticity is presented in the paper. The boundary condition considering the surface stresses, which are originated from surface energy, was employed for the surfaces of indenter and substrate. Furthermore, it was supposed that the surface stresses in an adhesion region are different from that in non-adhesion region and decrease from the original surface stresses. The results in the analysis were compared with those in the Hertz theory. The deformation near the adhesion region and the total force for the radius of adhesion region are presented.
