Charles Babcock (1935–1988) (MS 1958 PhD 1962; student of Sechler) Professor of Aeronautics and Applied Mathematics, 1963–1988. Reconciled theory and experiments on buckling of cylindrical shells through the use of exceedingly closely toleranced shells (electroplating process) and control of the edge boundary conditions. Used imperfection theory to place the problem of shell stability and structural reliability on a different level. Applications to buckling of large liquid storage tanks under earthquake conditions and collapse of sea-bed deployed oil pipe lines. Knauss and Babcock studied the important problem of layer delamination in damaged composite panels under in-plane compression from a combined fracture mechanics and bucking point of view. Vice Provost of Caltech under R. Vogt until Babcock's untimely death in 1988.
