Apparatus for an anvil system that provides enhanced self-resistive specimen heating when used in a dynamic thermo-mechanical material testing system

Apparatus for use in a conventional dynamic material testing system to advantageously provide uniform self-resistive specimen heating with enhanced temperature uniformity. Specifically, an anvil stack ( 300 ) in an anvil assembly ( 200 ) has a foil interface ( 242 ) with a composite layer ( 320 A ,...

Zusammenfassung:Apparatus for use in a conventional dynamic material testing system to advantageously provide uniform self-resistive specimen heating with enhanced temperature uniformity. Specifically, an anvil stack ( 300 ) in an anvil assembly ( 200 ) has a foil interface ( 242 ) with a composite layer ( 320 A , 320 B , 320 C) containing, e.g., a concentrically oriented multi-component arrangement formed of an inner high strength and insulating disk ( 315, 325, 335 ) and an outer ring-shaped resistive region ( 313, 323, 333 ), situated between an anvil base ( 241 ) and an anvil top ( 240 ). An insulating member ( 243 ) electrically and thermally insulates all sides of the anvil stack from its supporting structure.
