SPHERE, a Program for Computing Buckling Loads of Spherical Shells under uniform Pressure.

Abstract

SPHERE is the PL/I, double precision, computer program used to implement the theory on 'Instability of thin-walled spherical structures under external pressure' by Harry E. /Rauch in 'Contributions to Analysis,' Academic Press, New York 1974. It can be adapted quickly to solve any programmed system of simultaneous non-linear (algebraic or transcendental) equations in as many unknowns as the number of equations. SPHERE is based on the algorithm given in 'a globally converging secant method with applications to boundary value problems' by E. Polok in SIAM J. Num. Anal., 11 (1974), pp. 529-537. It is a modified Newton-secant method combined with the method of local variations. (Author)
