1. A method of manufacturing a part, the method comprising:
positioning a first material within a cavity of a die such that the first material is in contact with a first surface of a base of the die;
positioning a stress transmitting material within the cavity of the die between a surface of a plunging component and the first material; and
uniaxially applying pressure to the first material with the plunging component via the stress transmitting material until the first material forms a desired shape, wherein the stress transmitting material is configured to change shape in response to the pressure from the plunging component as it transmits substantially uniformly distributed force to the first material.
