Abstract :This manuscript describes how the weight of a simply supported composite plate-strip insert ignore into journalissuearticles values(containing twin circular inclusions); affects its dynamic behaviors when exposed to bending load as analyzed via the finite element method insert ignore into journalissuearticles values(FEM);. The centers of the twin circular inclusions are on a line parallel to the free surface, and the materials of both inclusions are the same. First, the effects of body forces insert ignore into journalissuearticles values(the plate-strip’s own weight); and surface forces insert ignore into journalissuearticles values(pre-stretching load); on the plate-strip insert ignore into journalissuearticles values(both are considered to be initial stresses); are identified using the classical linear theory of elasticity. Next, the consequences of these stressors insert ignore into journalissuearticles values(identified in the first step); under additional time harmonic bending load on the forced vibration around the inclusions are determined using the three-dimensional linearized theory of elasticity insert ignore into journalissuearticles values(TDLTE); under the plane-strain state. The data herein suggest that the plate-strip’s weight can significantly effect dynamic characteristics of the considered plate-strip.
