“…To calculate the values for the definite integrals, the Gauss Quadrature method was employed, and included 10 sample points. For ease, and so that the numerical values around the circular inclusions could be better understood, the cylindrical coordinate system (Orθx 3 ) was used to determine the stress values [12]).…”

“…Previous studies [8][9][10][11] that performed dynamic analyses on plates and beams with an approximate closed-form solution of the structures took the influence of dead loads into account. The effect of the weight of a pre-stretched plate-strip containing a circle-shaped hole on static analysis were studied in Babuscu Yesil [12]. Other studies analyzed the effect of dead load on the dynamic behaviors of beams Zhou and Zhu [13] and plates Zhou [14] using the concept of load-induced stiffness matrix via the finite-element method.…”

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.

“…The validated FEM is used to perform the temperature-dependent buckling analysis of open-hole glass fiberreinforced epoxy (GFRE), glass fiber-reinforced polyester (GFRP), carbon fiber-reinforced epoxy (CFRE), and carbon fiber-reinforced polyester (CFRP) composite plates. In other literature, studies of open-hole and perforation effects on composites' and metals' structural properties have been addressed in detail (cf, [13][14][15][16][17][18][19][20][21]).…”

Understanding the buckling behavior of fiber-reinforced composites (FRCs) is critical for the design of composite structures. In this study, finite element (FE) models of FRC buckling behaviors were developed and validated. The validated FE models could accurately predict the numerical and experimental observations in the literature. The effect of the specimen geometric imperfections was included in the model to secure a realistic FE model; to this end, linear buckling analyses were employed before beginning the nonlinear buckling analyses. The FRCs’ mechanical properties and the buckling behavior of FRCs can be temperature-dependent. Because the presence of a hole in the design of composite structures may be inevitable in a few applications, the temperature-dependent buckling responses of open-hole glass/epoxy, glass/polyester, carbon/epoxy, and carbon/polyester composites were compared with those of the plain specimens. The effects of the fiber and resin types, temperature, and the presence of holes on buckling behavior were investigated and discussed in detail. Five different temperatures 25, 0, -50, -100, and -180 oC were considered. The cryogenic temperatures raised Young’s moduli and consequently raised the critical buckling loads. The validated models and results on the open-hole composites can be used as benchmarks in composite structure designs involving buckling behavior.
