## Abstract

Among other things, a heating jacket configured for heating a mechanical testing instrument having a probe is disclosed herein. The heating jacket includes a heating element including a jacket wall, and the jacket wall extends around a probe recess, the jacket wall is configured to receive a probe of a mechanical testing instrument within the probe recess, and the heating element is mechanically isolated from the probe with a probe gap. Additionally, a system to correct for thermomechanical drift in a mechanical testing assembly is disclosed herein. The system isolates the mechanical testing instrument from thermomechanical drift of a system frame using a determined difference between, for instance, a probe displacement and a sample displacement.
