Abstract The stress distribution in cylindrical shells with light frames is very different from the conventional beam distribution in the neighborhood of the applied loads. The problem is examined hereafter for circular cylinders with circular frames of constant section. The case of an indefinite shell with one loaded frame is examined in detail, and diagrams are given for the following unit conditions: Concentrated radial force, tangential force, couple.

There is an increasing usefulness of exact three-dimensional analyses of elastic cylinders and cylindrical shells in composite materials applications. Such analyses are considered as benchmarks for the range of applicability of corresponding studies based on two-dimensional and/or finite element modeling. Moreover, they provide valuable, accurate information in cases that corresponding predictions based on that later kind of approximate modeling is not satisfactory. Due to the complicated form of the governing equations of elasticity, such three-dimensional analyses are comparatively rare in the literature. There is therefore a need for further developments in that area. A survey of the literature dealing with three-dimensional dynamic analyses of cylinders and open cylindrical panels will serve towards such developments. This paper presents such a survey within the framework of linear elasticity.

Minimization Technique

Nonlinear equations are derived for the axisymmetric deformation of thin, cylindrical shells made of Mooney-Rivlin materials and subject to arbitrarily large strains and rotations. These equations are then implemented numerically using an energy minimization technique. Finally, an extensive parametric analysis is done of cylindrical shells which are clamped at one end and loaded with either a radial force or an edge moment uniformly distributed along the circumference of the other end.

Kinetics Of

The softening kinetics of a 0.19 wt% C 1.5 wt% Mn steel deformed at two intercritical temperatures have been characterised using the stress relaxation technique. Recrystallisation of intercritical austenite has been modelled using a single grain model (Chen et al., 2002 [1]), whilst recovery of both intercritical austenite and ferrite has been modelled using a model in the literature [Verdier et al., 1999 [2]). The models are combined to predict the overall softening kinetics with a rule of mixtures formulation. Comparison of the model with experiment shows significant deviations. The reasons are discussed with reference to the mixture rule and to the local stress-strain distribution which exists in the deformed samples. A simple modification to the model is proposed which takes into account the effect of a local stress distribution in deformed austenite.

Bottom Slab

Based on summarizing the purpose and main working conditions of horizontal analysis of the box beam in bridges, combined with the force status of the chambers under the radial force of the bottom slab in Zhaohua Beijiang Bridge, the stress distribution in the cross-section under the pre-stressed radial force of the bottom slab at the center of a span of 210m and 85m respectively is analyzed with finite element method. The horizontal and vertical stress distribution and chambers displacement under the radial force are respectively researched. The results show that appropriate size should be used in the angle between both sides and the end of a box beam with a large span; the box beam lower, the girder webs bending stress generated by the radial force greater; the bending stress of the webs weakens their own principal stress state. These conclusions have certain significances for the study of the box girder stress, deformation and crack control.
