“…and V n represents the area of the n th finite element and selected as curved triangular finite elements with 6 nodes (including the surrounding area of the inclusions and the inclusions domains) and biquadratic quadrilateral Lagrangian elements with 9 nodes (for the domain not included with the triangular elements) (Figs. 2a and 2b) [6], [18]. The displacement-based formulation is used for the FEM modeling.…”

This manuscript describes how the weight of a simply supported composite plate-strip (containing twin circular inclusions) affects its dynamic behaviors when exposed to bending load as analyzed via the finite element method (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 (the plate-strip's own weight) and surface forces (pre-stretching load) on the plate-strip (both are considered to be initial stresses) are identified using the classical linear theory of elasticity. Next, the consequences of these stressors (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 (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.

“…Detailed studies have reported the effect of initial stretching on a plate with twin inclusions on forced vibration analysis in Babuscu Yesil [6] and Akbarov [7]. However, these previous studies did not take into account the object's weight, and therefore, all structures (both heavy and light) were considered equal.…”
