Popis: A calorimetric technique has been developed to simultaneously measure the heat and work of solid deformation. The physical construction of the instrument is similar to previously reported deformation calorimeters which operate as null or compensating devices, utilizing features of differential gas thermometry and hot‐wire methods of measuring thermal conductivity. The present method combines the quick response time and high sensitivity of such devices with a direct measurement principle which greatly simplifies data acquisition. Theory and operation of the instrument are discussed and some data on a polyurethane elastomer are presented.
