“…Consider a symmetrically or anti-symmetrically laminated rectangular plate of length a, width b, central circular hole of diameter d and thickness t which consists of six orthotropic laminas [12]. In this study, first-order shear deformation theory (FSDT) is employed to analyse the problem and the following displacement field is assumed [8,10]…”

In this research, buckling behavior of perforated rectangular plate of symmetric and anti-symmetric laminated composite is investigated based on Finite element analysis. The presence of hole may cause redistribution of stresses in plates with reduction of stability. The aim of the current paper is to find critical buckling load by using the (FSDT) first-order shear deformation theory in concomitance with the variational energy method. The load depends on many factors like as diameter of circular hole, different boundary conditions, lay-up sequences, length/thickness ratio and angle of ply orientation. The result is shown in graphical forms for various boundary conditions.

“…Accepted pattern consists of O node and E ± ij points, separated from the point O by distance λ ij τ . In the future discussion values of the functions at the point O are denoted by upper index "0", values at the points E ± ij are denoted by lower index "ij" and the upper index "±" (for example σ ± ij ), and values at point A are not not denoted by an additional index [13][14][15][16].…”

This paper describes the numerical method for the solution to the problem of propagation of dynamic waves in elastic media -the bicharacteristics method with the usage of the ideas of the splitting method. The bicharacteristics method is one of the most convenient methods for software creating. In this research paper we have worked on the solution for non-stationary problem of the homogeneous isotropic elastic body dynamics using the bicharacteristics method, based on which the "ProgWave" software was designed. With this software, we have obtained the plots of isolines of normal and tangent tensions, which are very important for the studies of non-stationary dynamic waves propagation in flat elastic bodies, in engineering practice at construction designs calculation, in problems of mechanical engineering, etc.
