Isotropic laminated plate containing a coated rigid elliptical inclusion subjected to a rotational moment with constant interfacial and hoop stress resultants

摘要

We consider the problem of a rigid elliptical inclusion bonded to an infinite Kirchhoff isotropic laminated plate through a coating layer with two confocal elliptical interfaces. The rigid inclusion is subjected to a rotational moment, while the infinite (plate) matrix surrounding the coated inclusion is subjected to uniform remote membrane stress moments and bending moments. We find that the interfacial and hoop stress resultants are uniformly distributed along the inclusion–coating interface provided a set of four conditions on the rotational moment and remote loading are satisfied for specified material and geometric parameters characterizing the three-phase composite plate.
