OSR-SPONSORED STUDIES ON UNSTEADY AERODYNAMIC AND NONLINEAR STRUCTURAL PROBLEMS OF AIRCRAFT AT MIT, 1957-1960

Abstract

The principal areas of effort presented under the aerodynamic phase are the following: the shock layer adjacent to an oscillating blunt nose in a hypersonic airstream; Prandtl-Meyer expansions in dissociational equilibrium; unsteady transonic airloads in the presence of a strong shock; the stability of combustion zones; the boundary-layer under conditions of time-dependent external flow; and radiation effects in hypersonic flow of real gases. The principal topics treated under the structural phase are the following: large deflections of curved strips and plates under thermal and pressure loadings; deflection and snap buckling of shallow spherical shells; yield conditions of plates and shells under combined bending moments and membrane stresses; inelastic diffusions of stiffened panels; dynamic response of rigid-plastic curved beams; dynamic buckling of shallow spherical shells; straight-crested waves in plates; and finite deflections of shallow arches taking shear deformation into consideration.
