Abstract: A theoretical study is made on the local ovaling of a relatively thick tube of low modulus caused by bending. Use is made of modified Donnell’s large-deflection theory [3] and the principle ...

Abstract: This paper presents a theoretical solution to the problem of determining the buckling characteristics of an axially compressed, long, cylindrical shell which contains a solid or elastic core ...

Abstract: The problem of a long, thin cylindrical shell with a soft core and subjected to a radial ring load is solved with the use of the Boussinesq-Neuber stress function for the core in conjunction ...

Abstract: Two nonlinear problems relating to buckling and parametric excitation of thin elastic cylindrical shells are considered. In the first, time-dependent end displacements are specified and, in the ...

Abstract: Current seismic design philosophies require an earthquake-resistant building capable of resisting strong motion for structures and nonstructural elements. In response to the need to understand the seismic behavior of ...

Abstract: To investigate the roof stability of deep cavities in layered soils, an axisymmetric failure mechanism based on the existing mechanism is proposed. Because deep cavities are generally under the water table, the adverse ...

Abstract: The improved model developed in Part 1 for predicting heat losses and pressure changes in steam injection wells is evaluated. It shows good agreement with limited field data. The improved model ...

Abstract: The characteristics of inertial drift eliminators of wet cooling towers are studied parametrically for their blade shapes, orientation with respect to gravity, solidity ratios, blade sizes, ...

Abstract: An improved model for predicting heat losses and pressure changes in steam injection wells is presented. The model incorporates a new two-phase, annular-mist flow pressure change model with heat ...

Abstract: A numerical model is developed to simulate the dynamics of the droplet-wall interaction and heat transfer mechanisms at sub-atmospheric to elevated ambient pressures, and for surface temperatures ...
