“…Calculation of the shear correction coefficient can be performed by using various methods. Some approaches have been discussed in (Vlachoutsis, 1992;Rikards et al, 1994;Altenbach, 2000). Further in numerical examples the shear correction factor has the value 10(1+υ)/(12+11υ).…”

In this study, static analysis of the two-dimensional rectangular nanoplates are investigated by the Differential Quadrature Method (DQM). Numerical solution procedures are proposed for deflection of an embedded nanoplate under distributed nanoparticles based on the DQM within the framework of Kirchhoff and Mindlin plate theories. The governing equations and the related boundary conditions are derived by using nonlocal elasticity theory. The difference between the two models is discussed and bending properties of the nanoplate are illustrated. Consequently, the DQM has been successfully applied to analyze nanoplates with discontinuous loading and various boundary conditions for solving Kirchhoff and Mindlin plates with small-scale effect, which are not solvable directly. The results show that the above mentioned effects play an important role on the static behavior of the nanoplates.

“…After evaluation of the optimum values of x, the remaining mechanical properties are calculated by inverse relations (3). The eigenvalue problem (13) was solved by the subepace iteration method [20] and using a triangular finite element of a laminated thick plate with the shear correction [21]. A 20 x 24 regular mesh (960 finite elements) was considered in order to achieve the necessary accuracy for at least the first 14 eigenvalues of the laminated plate with FFFF boundary conditions.…”

A numerical-experimental method for the identification of mechanical properties of laminated polymeric composites from the experimental results i~ being developed. For the first time, it is proposed to use the method of experiment planning to solve the identification (inverse) problems. The basic idea of the approach i~ that simple mathematical models are determined only from information on the response of a structure in reference points of the design. Therefore, a significant reduction in the calculation of the identification functional (about 50-100 times) can be achieved in comparison with the conventional methods of minimization. Examples of the numerical identification of the elastic properties of the laminated composites from the measured eigenfrequencies of plates are discussed.
