Abstract:

The report deals with the stress and strain distribution around a circular bar embedded in a matrix and subjected to a mechanically applied triaxial load. The three-dimensional freezing technique of photoelasticity was used. The results obtained correspond to the case of a rigid circular bar embedded in an homogeneous, elastic matrix. Two models were analyzed in one the axis of the circular bar was parallel to the direction of the loading and in the other the axis of the circular bar was normal to the direction of loading. By combining the results obtained independently for these two cases, stress and strain distribution around the circular bar for various ratios of triaxial load can be obtained. Author
