N2 - In order to quantify the influence of large voids on the unconfined compressive strength (UCS) of macroporous materials, fifty-four 3″×6″ plaster cylinders have been created, containing up to twenty-four 1″ diameter spheres representing large voids. The UCS of each specimen is being determined in the laboratory, after which the specific location of each of the spheres is found. A FLAC3D numerical model is then created for each specimen, and the UCS determined via numerical simulation of the laboratory test. To date, 17 specimens have been tested in the laboratory, and three numerical models have been completed. Although the numerical and experimental results do not agree perfectly, the UCS values determined in the laboratory are lower than the numerically determined UCS values, as expected. The new results, both numerical and experimental, are within the range of data previously collected.
