Effect of Boundary Conditions on Non-linear Static Buckling of Laminated Composite Pentagonal Plate Made of Aloe Vera Fibers

The demand for lightweight and high-strength materials is becoming more and more these days and this is achieved by the help of laminated composite panels. These panels have specific strength and specific stiffness. Due to this, they can be used for various application in aerospace, biomedical, automobile and civil engineering fields. The use of natural materials is required in view of sustainability characteristics. Understanding how boundary conditions influence buckling is crucial for optimizing the performance of composite structures. Engineers and designers need accurate predictions of when and how buckling may occur so as to assure reliability additionally security of parts. Moreover, the incorporation of natural fibres introduces an environmentally friendly aspect to the research, as these fibres are renewable and biodegradable, aligning with sustainable material choices. The design and manufacturing processes of laminated composite pentagonal plates with natural fibres. By identifying which boundary conditions lead to enhanced buckling resistance or improved post-buckling behaviour, the study aids while choosing knowledge appropriate materials and structural configurations. This effort not only advances the fundamental understanding of composite mechanics but also holds the potential to advance the development of lightweight, durable, and environmentally conscious materials for a wide range of engineering applications. The effect of boundary conditions in laminated composite plates is evaluated in this study using numerical method. The cross-ply laminated composite pentagonal plate considered for the study is made of natural fibres. First the convergence and validation studies are carried out using the available results from the literature. Then, the frequency response and linear static buckling loads are evaluated for the plates.
