“…However, after the introduction of semiloof shell element, dealing with analysis of thin shelled structures with sharp corners and multiple junctions gave more accurate and suitable results. Semiloof element has been successfully applied for several structural problems: stress [2], thermal stress [3,4], buckling [5], thermal buckling [4,6,7], free vibration [8,9], initially stressed vibration [8,9], non-linear vibration [10], geometric non-linear analysis [11], and piezo-electric active elements [12]. The same element has been implemented for different material properties: Isotropic, Composite [5,8,13], and FGM [9,10].…”

In this research article, semiloof shell element was used to study the behaviour of plate and shells under mechanical and thermal load for stress, free vibration, initially stressed vibration, mechanical buckling, and non-linear vibration. In the above cases, the material properties: Isotropic, Composite and Functionally Graded Material (FGM) were considered. Wherein, the material property for the FGM shells was assumed to vary through the thickness of the shell by varying the volume fraction of the constituent, whereas, for composites, classical laminated theory was used. Utilizing the semiloof shell element, and the above material properties, the package COMSAP was developed. From the obtained results, we have observed that with coarse meshes, semiloof shell elements present better results, and it is especially effective in the case of thin plates and shells.

Finite element formulation using semiloof shell element for initially stressed vibration of Functionally Graded Material (FGM) plates and shells are presented. The influence of volume fraction index on the vibration frequencies of thin functionally graded plates and shells and variation of temperature on frequency are studied. New results are presented for initially stressed vibration of FGM plates and shells.

“…The fundamental natural frequency of composite laminated plates subjected to compression highly depends on the ply orientation (Noor and Burton [1], Tenek [2], Chen et al [3], Chakrabarti et al [4]), end conditions (Chakrabarti et al [4], Dhanaraj and Palanininathan [5], Sundaresan et al [6], Nayak et al [7]), aspect ratio (Chen et al [3], Chakrabarti et al [4]), thickness (Chen et al [3], Chakrabarti et al [4], Nayak et al [7]), cutout (Tenek [2]), and compressive force (Chen et al [3], Chakrabarti et al [4], Dhanaraj and Palanininathan [5], Nayak et al [7]). Therefore, proper selection of appropriate lamination to maximize the fundamental frequency of composite laminated plates in compression becomes a crucial problem (Bert [8], Abrate [9], Raouf [10], Topal and Uzman [11]).…”

Free vibration analyses of rectangular-and square-composite laminated plates subjected to uniaxial compressive forces are carried out by employing the ABAQUS finite element program. The fundamental frequencies of rectangular-and square-composite laminated plates with a given material system are then maximized with respect to fiber orientations by using the golden section method. Through a parametric study, the significant influences of end conditions, plate aspect ratio, circular cutout, and compressive force on the maximum fundamental frequencies and the associated optimal fiber orientations are demonstrated and discussed.
