Abstract:

The non-symmetrical snap uckling of uniformly loaded clamped spherical caps is computed by an energy procedure. Non-symmetrical buckling is shown to govern when the geometrical parameter that represents the steepness of the cap exceeds a partic lar value. Single term approximations are used to represent the initial and buckled shapes which, although showing the general features of the problem, do not lead to fully reliable numerical values. A more accurate analysis that includes the development of a boundary layer in the cap is used to compute the equal energy buckling load. The significance of the energy load as a lower bound on buckling loads is discussed. Author
