Landel to receive Charles Goodyear Medal.
Robert F. Landel, a polymer physical chemist and rheologist, retired from the CalTech Jet Propulsion Laboratory, will receive the Charles Goodyear Medal at the Rubber Division's Science and Technology Awards Banquet. His research concentrated on experimental examinations of the time, strain and temperature dependence of mechanical properties of fluid and crosslinked polymers, both filled and unfilled. His group devised novel planar biaxial and torsion-tension equipment and was the first to clearly determine the major revelation that time and strain contributions to response were not intermingled under these conditions, but independent factors. Landel and K.C. Valanis developed a form of stored energy function for the description of large deformation, multiaxial, non-linear response in use conditions of rubbers.
