Sammanfattning
Advancement in technologies opens new ways to retrofit conventionally used material in the world. Due to recent rise in importance of sustainability and environmental preservation construction industry is obliged to switch to materials like Fibre reinforced polymers (FRP). Fibre reinforced polymer is a composite material made up of continuous fibres packed together with a resin. These fibres and resins can be made from different materials. For example, fibres are made of Glass or Carbon and resins can be epoxy or polymer based. FRP is used when high stiffness, high tensile strength and light weight design aspects are basic requirements in a structural component. Preliminary design codes need to be specified for FRP to standardize the material in this globalization era. Euro codes has many grey areas in stability of FRP composites under buckling.
Aim of this master’s thesis is to develop buckling behaviour of FRP plates when subjected to uniform in-plane compression with specific boundary conditions, similar analysis is carried out with a hole in the middle of the plate in finite element solver “ABAQUS”, only glass fibre polymers are used in this analysis. To standardize the new stability findings, a similar analysis to steel is made i.e., to extract a relation between buckling reduction factor and slenderness. Different matrices are created with different layups, thicknesses, and initial imperfections to extend the range of the study to match the real-world implications.
