A closed loop servohydraulic testing system for determining the room temperature stress-strain behavior of plastically isotropic materials at constant true strain-rate has been developed. Analog outputs from the system are capable of plotting the true stress-true strain curve autographically. Results are shown for Type 304 stainless steel and 1008 steel tested at strain rates from 10/sup -3/ to 10/sup -1/ s/sup -1/. Techniques for extending the system capability to elevated temperature testing of plastically anisotropic material are discussed. An analysis has been developed for determining the thermoelastic properties of an anisotropic polycrystalline material from single crystal data on the thermal expansivity and elastic constants and pole figure information. The effect of texture on the predicted anisotropy of yielding behavior for several assumed yield conditions has been determined. It is shown that anisotropy can have a large effect on the initial yielding behavior of zircaloy-4.
