The current review covers numerical analysis using Matlab program for multi-layer composite materials. Which involves studies are related to the intersection with fibers, between layers and piezoelectric layer or patch. It has been reported that a great flexibility in due its library which includes various methods. In addition ability of programming developing finite element technology calculat...

Fundamental frequencies of solid and annular elliptical plates were approximated using the static deflections by means finite element method (FEM) without computing eigenvalues. The problem was formulated within framework first order shear deformation theory (FSDT). effects (i) inner outer boundary conditions, (ii) size perforation, (iii) aspect ratio, (iv) thickness plate on performance examin...

in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are so...

in the present work, study of the vibration of a functionally graded (fg) cylindrical shell made up of stainless steel, zirconia, and nickel is presented. free vibration analysis is presented for fg cylindrical shells with simply supported-simply supported and clamped–clamped boundary condition based on temperature independent material properties. the equations of motion are derived by hamilton...
