Abstract
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 (320A, 320B, 320C) 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.
