Stress distributions calculated for thin disks having a cylindrical inclusion were found to agree with those measured for glass specimens cooled to room temperature after they were sealed. Maximum circumferential stress in the sheath was independent of inclusion size, but the more rapid decrease of this stress with distance from the inclusion makes crack extension from the interface impossible for inclusions below a certain size. For larger inclusions, flaws above a critical size can be expected to grow and to terminate after a certain distance.
