Buckling analysis of inflatable composite beams
ABSTRACTThis thesis presents a numerical modeling and an experimental program approach to investigate the buckling behavior of inflatable beams made f Buckling analysis of inflatable composite beams from woven fabric composite materials.In the numerical study, the Isogeometric Analysis (IGA) is utilized to analyze the bucking response of inflatable beams subject to axial compressive load and predict the critical load at which the first wrinkle occurs. In the numerical model. Timoshenko's kinema Buckling analysis of inflatable composite beams tics principle is used to build a 31) model of inflating orthotropic beams. In this modeling process, geometrical nonlinearity is considered by usingBuckling analysis of inflatable composite beams
