Abstract : Hydrostatic tests were conducted on forty fabricated HY-80 steel hemispheres and ellipsoids to study the effects of initial imperfections, residual stresses, and penetrations on the elastic behavior and collapse strength. By using critical local geometries rather than nominal geometries, definite patterns in test results are shown. The importance of accurate and detailed determination of local geometries is demonstrated. (Author)
