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.

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.

Reinforcing Ribs

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.
