1. A method comprising:

  • attaching a double-ended tuning fork to a first reference material;

    attaching a second double-ended tuning fork to a second reference material;

    applying a pre-defined thermal test scenario to the first and second materials;

    recording output of the first and second double-ended tuning forks produced during the thermal test scenario; and

    determining a relative stress value between the first and second materials based on the recorded outputs of the first and second double-ended tuning forks.
