"Uniaxial compressive strength for two and three-layered specimens was obtained with different thicknesses of layers and also for different length to diameter ratios. The fracture and failure pattern was studied. Shear and extension fractures were observed in the layers. Geometry and end conditions of the specimen had a great influence in the failure and fracture pattern.
The uniaxial compressive strength of a layered specimen was found to be lower than the weighted average strength and either low or high when compared to the arithmetic average strength, depending on the ratio of the heights of the layers. The compressive strength of a layered specimen increases as the ratio of length to diameter decreases. The influence of the number of non-cohesive interfaces on compressive strength has also been observed. Suggestions are made for calculating the compressive strength of a layered pillar"--Abstract, page ii.
