Panagiotopoulos, P. D. Semicoercive hemivariational inequalities. On the delamination of composite plates. (English) Zbl 0693.73007 Q. Appl. Math. 47, No. 4, 611-629 (1989). (Author’s summary.) In this paper semicoercive hemivariational inequalities are studied in the framework of a concrete mechanical problem: the delamination effect of laminated plates. The interlaminar bonding forces are described by a nonmonotone multivalued law which may be written at the generalized gradient of a nonconvex superpotential in the sense of F. H. Clarke [e.g.: Adv. Math. 40, 52-67 (1981; Zbl 0463.49017)]. Then necessary conditions are proved for the existence of the solution, as well as sufficient conditions using compactness and average value arguments.
