Bending and vibration analysis of multi-folding laminate composite plate using finite element method

Abstract

Abstract. This paper deals with the bending and vibration analysis of multi-folding laminate composite plate using finite element method based on the first order shear deformation theory (FSDT). The algorithm and Matlab code using eight nodded rectangular isoparametric plate element with five degree of freedom per node were built for numerical simulations. In the numerical results, the effect of folding angle on deflections, natural frequencies and transient displacement response for different boundary conditions of the plate were investigated.

Free vibration of basalt fiber reinforced polymer (FRP) laminated variable thickness plates with intermediate elastic support using finite strip transition matrix (FSTM) method

“…Al-Tabey [11] presented the finite strip transition matrix technique (FSTM) and semi-analytical method to obtain the natural frequencies and mode shapes of symmetric angle-ply Graphite/Epoxy laminated composite variable thickness rectangular plate with classical boundary conditions (SSFF). Thinh et al [12] examined the bending and vibration analysis of multi-folding laminate composite plate using finite element method based on the first order shear deformation theory (FSDT). They investigated the effect of folding angle on deflections, natural frequencies and transient displacement response for different boundary conditions of the plate.…”

High performance estimations of natural frequency of basalt FRP laminated plates with intermediate elastic support using response surfaces method

“…Continuous and with intermediate stiffeners plates) are most common in a wide range of engineering fields such as aerospace, structures, vehicles and marine industries. In general, the approximate [1][2][3][4][5][6][7][8][9][10] or numerical [11][12][13][14] method must be used to compute the natural frequencies and find mode shapes for different boundary conditions for plate ends.…”
