摘      要：The experimental study in this paper focuses on the effects of the layer orientation and sample shape on failure strength and fracture pattern of samples tested under Brazilian test conditions(*** loading of cylindrical discs)for one particular layered sandstone which is from Modave in the south of *** variations of the strength in combination with the failure patterns are examined as a function of the inclination angle between the layer plane and the loading *** experimental,results clearly show that the induced fracture patterns are a combination of tensile and/or shear *** shape effect experiments the layer thickness and the number of layer boundaries are *** blocks of Modave sandstone are used to prepare *** layer thickness is different among the various blocks,but the layer thickness in each studied rock block can be considered to be constant;hence,the number of layer boundaries changes according to the sample diameter for samples of the same *** experimental study shows that the layer thickness plays a more important role than the number of layer boundaries per sample.
