[구조강도부문] T형 보강재로 보강된 복합적층 원통형패널의 최적설계

In this study. using linear and nonlinear deformation theories and by c1osed-form analysis and finite difference energy methods. respectively. various buckling load factors are obatined for stiffened laminated composite cylindrical panels with T type longitudinal stiffeners and various longitudinal length to radius ratios. which are made from Carbon/Epoxy USN 150 prepreg and are simply-supported on four edges under uniaxial compression. and then for them. buckling behavior design analyses are carried out by the nonlinear search optimizer.
