... His wide-ranging and groundbreaking research spanned creep of crystalline solids; internal friction, fatigue, and fracture of metals; dislocation theory; geothermal energy; mechanics of glaciers; and stability of ice sheets, among others. Hans was born May 11, 1925, to Roelof "Rudy" and Christina van Vlaardingen Weertman in Fairfield, Alabama.
From page 392...
... With NU colleague Morris Fine (NAE 1973) , the Weertmans contributed to and edited volumes in the early 1960s Macmillan Series in Materials Science based on graduate courses offered at NU.
From page 393...
... Spending his summers at Los Alamos he did technical work that led to DOE-funded geothermal research at NU with colleagues in the Chemical and Mechanical Engineering departments. In 1975 he wrote "Water pumped into the deep earth to make steam causes fracturing of rock"3 -- words familiar in today's world of oil and gas extraction by "fracking." His early work in this field remains "ground­breaking"!
