Abstract:
A finite element method is developed for the large deflection elastic-plastic analysis of axisymmetric shells of revolution. Results were obtained for a torisphere under internal pressure and also for centrally loaded spheres. A study was made of the effect of elastic-plastic behavior on the buckling of spheres with axisymmetric imperfections subjected to external pressure. It was found that plastic yielding played a significant role in reducing the buckling pressure of these shells. The influence of plastic yielding increased with increase of the thickness to radius ratio. Author
