The three-dimensional stress-strain state of an isotropic plate loaded on all its surfaces is considered in the article. initial problem divided into two ones: symmetrical bending and a compression plate, by specified loads. It shown that plane theory elasticity special case second task. To solve task, symmetry normal stresses used. Boundary conditions are satisfied harmonic obtained for some f...

Abstract: In this paper we solve a simple dead load problem for an isotropic constrained material according to the linearized finite theory of elasticity. We show that the solution of such a problem can be obtained by linearizing with respect to the displacement gradient the solution of the corresponding problem in finite elasticity for an isotropic material subject to the same constraint, exac...

this study has aimed to investigate the effect ofthree-dimensional and two-dimensional video games on problem-solving styles ofstudents. statistic society in this study consisted of persian gulf universitystudents in 2016-2017 academic year. and after notification by theproclamation, 45 students were selected voluntarily. at first all 45 students,completed intelligence test and past the experie...

A variational limit defined on the space of one-dimensional Young measures is obtained from three-dimensional elasticity via dimension reduction. The physical requirement that the energy becomes infinite when the volume locally vanishes is taken into account. The rate at which it blows up characterizes the domain of the limit energy. The obtained limit problem uniquely determines the energy den...

This paper deals with free vibration analysis of thick Laminated curved panels with finite length, based on the three-dimensional elasticity theory. Because of using two-dimensional generalized differential quadrature method, the present approach makes possible vibration analysis of cylindrical panels with two opposite axial edges simply supported and arbitrary boundary conditions including Fre...

In this paper we consider a nonlinear two-phase Stefan problem in one-dimensional space. The problem is mapped into a nonlinear Volterra integral equation for the free boundary.
