This paper is a summary of a series of five research programs dealing with the experimental determination of stresses, strains, and displacements in circular cylinders subjected to pressure. The vessels have either constant thickness or transverse reinforcing ribs. Circular holes, with either plain or reinforced edges, are located in different positions of the vessels. The methods used for the analysis are: brittle coatings, three-dimensional photoelasticity ("freezing" technique), and electrical and mechanical strain gages. The most important results are summarized in a table. These results will be of interest to designers of underwater ships and of pressure vessels in general.

Stress Concentration Factors

The boundary integral equation (BIE) method for three-dimensional linear, elastic stress analysis is applied to some stress concentration problems associated with transverse circular holes in either hollow or solid circular cylinders subject to axial tension or torsion, also offset-oblique holes in cylinders subject to internal pressure. Satisfactory agreement is obtained with some previously published experimental results, although computed maximum stress concentration factors are generally higher than those obtained experimentally. The BIE method is shown to be a very useful tool for solving three-dimensional problems of engineering stress analysis.

ABSTRACTA closed-form solution for a macroscopically homogeneous, fully anisotropie layer subject to non-uniform through-thickness eigenstrain is presented, and employed in determining the three-dimensional deformation and stress states of a thermally loaded ceramic film with microstructure-induced macroscopic anisotropy. The resultant stress field is compared with those that could be deduced by experimental determination of the curvature and the classical structural theories.

Long Cylinder

An analytical procedure applicable for the experimental determination of initially existing residual stresses in long composite circular cylinders is derived within the framework of the drilling and turning technique. The method is demonstrated for a long cylinder composed of two different materials. An extension to cylinders composed of an arbitrary number of circular cylindrical layers can easily be derived in analogy to the described procedures.

The results of laboratory studies of the effect of thawing conditions (plane-parallel or three dimensional) on the deformation characteristics (thawing and compression coefficients) thaw- ing soils (sand, sandy loam, clay loam) with desired physical properties of massive and layered cryogenic textures presented in the article. It was found that the values of the thawing coefficient bigger after three dimensional thawing, and compression coefficient after plane- parallel thaw- ing. The obtained data allowed to establish the applicability of the experimental determination of thawing soils deformation characteristics regardless of thawing conditions.
