ABSTRACT:
A machine that can be used for loading of a slotted specimen for measuring the fracture toughness, fatigue crack growth resistance, or stress corrosion crack growth resistance of that specimen, the machine having a pressure bag maintained in a frame, which pressure bag can be installed within the slotted portion of the specimen and expanded to produce a desired specimen loading, the machine preferably involving a load pressure sensing device, can optionally include an arrangement for sensing volume enlargement of the specimen slot, and can also include a movable frame portion that expands with the pressure bag during inflation to discourage crimping of that pressure bag during specimen loading.
