Abstract
An oven (1800) for use in conjunction with a dynamic thermal-mechanical testing system that exhibits both self-resistive and self-inductive heating whenever a sufficiently large alternating (AC) electrical current is passed through the oven. In one embodiment, the oven is fabricated from a material which undergoes self-resistive heating to radiantly heat an internal volume of the oven. The oven also includes appropriately shaped heating sections (1830), which undergoes self-resistive and self-inductive heating to compensate for heat losses into a support for the oven.
