Abstract
In one aspect, an apparatus includes a chamber configured to control one or more of humidity, pressure, or temperature and a jaw configured to flex a material system. The chamber includes an enclosure disposed within the chamber, the enclosure having an insulating material, and a motor or an actuator disposed within the enclosure. The chamber includes an inlet tube coupled with the enclosure at a first end and a first wall of the chamber at a second end. In one aspect, a method for determining material performance includes exposing a material system to a relative humidity of from 0% to 98% and flexing the material system at a first temperature in a chamber, the chamber comprising an enclosure disposed within the chamber and a motor disposed within the enclosure. The method includes operating the motor at a second temperature different from the first temperature during the flexing.
