Abstract: Under the different combinatory loads the thin titanium tube possesses different stress states. In particular, the anisotropy and biakial strengthening of TA2 titanium tube directly influences the reasonable design of the titanium tubular exchanger. Using the plastic potential theory and through different combinatory stress experiments, this paper proves the anisotropy and biaxial strengthening effect of TA2 titanium tube, and presents a reliable basis for the reasonable design of the titanium tubular e...
