A FORTRAN PROGRAM FOR CALCULATING THE SOUND RADIATION FROM PROLATE SPHEROIDS

Abstract

D CRIPTORS: (*Cylindrical bodies, Pressure, Me surement, hear tr s es, Stresses, Hydro static pressure.) (Elasticity, Plasticity, Buckling, Theory, Failure Mechanics), *Plastics, Tests, Stability.) (*Aluminum, *Steel, Equations, Mathematical analysis.) (*Model tests, Structural shells.)A theoretical derivation is given for elastic and plastic buckling of stiffened circular cylindrical shells und r external hydrostatic pressure. The theory accounts for variable shell stresses, as influenced by the circular stiffeners, and critical buckling pressures are obtained for simple support condition at the shell-frame junctures. M ETHODS ARE GIVEN FOR THE DETERMINATION OF COLLAPSE PRESSURES FOR BOTH EL STIC AND PLASTIC ASYMMETRIC BUCKLING BY INTERATION AND NUMERICAL MINIMZATION. The theory is applicabl to shells made either of strain-hardening or elastic-perfectly plastic materials. Using the theory, it is shown that a variation in stiffener size can change the buckling pressures. Test data from high-strength steel and aluminu cylinders are presented which show theoretical and experimental collapse pressures to agree within approximately 6 per cent. (Author)
