ABSTRACT:
Apparatus, and an accompanying method for use therein, for a dynamic material testing system, and particularly for one that tests a specimen by compressively deforming its work zone and that has independent control over specimen deformation (strain) and strain rate. The apparatus can also simultaneously direct resistance heat or conductively cool the specimen, under controlled conditions, in order to establish isothermal planes at a desired substantially uniform temperature throughout the specimen work zone before, during and after each compressive deformation thereof.
