Design of equipment for examination of compressive creep at constant compressive stress

Measurements of the compressive creep of AlZn specimens taken in simple laboratory equipment without correcting the acting compressive force during the change of the cross section of the specimen during its deformation showed that it is useful to supplement these measurements with other measurements taken in conditions of constant compressive stress. This work proposes the design of simple equipment. It can be produced in table form and its system (the frame, anvil, pressure rod) can be inserted in a thermostatically controlled bath.
