INFLUENCE OF BOUNDARY CONDITION ON COMPRESSIVE STABILITY PERFORMANCE OF STIFFENED THIN-WALL PANEL
Nonlinear finite element method（ FEM） was adopted to calculate the compressive stability of stiffened panel numerically. Simple support and clamped support of loaded ends as well as common used unloaded edge support fixtures,such as blade,bolt and rigid strip,for stability experiment were simulated...

| description | Nonlinear finite element method（ FEM） was adopted to calculate the compressive stability of stiffened panel numerically. Simple support and clamped support of loaded ends as well as common used unloaded edge support fixtures,such as blade,bolt and rigid strip,for stability experiment were simulated by defining node constraint conditions of 4 edges of stiffened panel finite element model. The influences of boundary conditions of loaded ends and unloaded edges on compressive stability of stiffened panel were analyzed according to the FEM calculational results. Calculational results show that,buckling load and carrying capability of panel with loaded ends clamped are bigger than those of panel with loaded ends simply supported. When loaded ends are simply supported,both buckling pattern and failure pattern vary with different unloaded edge boundary conditions,and buckling loads of panel with unloaded edges supported are bigger than that of panel with unloaded edge free.When loaded ends are clamped,both buckling pattern and buckling load are almost the same despite different unloaded edge boundary conditions,whereas carrying capabilities of panel with unloaded edges supported are bigger than that of panel with unloaded edge free. |
