Abstract : The report describes investigations of plates and shells under external loading and elevated temperatures, and includes problems of special interest to designers of missiles and aircraft. Chapter 1 discusses the analysis of the postbuckling (large-deflection theory) of noncircular (oval) cylindrical shells under axial compression and related experimental investigations, the application of exact finite deformation theory of three-dimensional elasticity to the stability problem of thick-walled cylinders under combined lateral pressure and axial compression, and investigations of nonlinear membrane shell problems. Chapter 11 describes work on the analysis of the effects of concentrated loads applied to reinforcing frames of finite and infinitely long circular cylindrical shells. Chapter 111 presents the results of investigations of the effects of creep in structures, with particular emphasis on the effects of line loads, the bending of variable thickness circular plates, and stress concentrations due to circular holes in large plates under uniaxial or biaxial loads.
