Flow stress of EK-181 steel as a function of the strain rate and the strain
Abstract
Branch pipes (segments of fuel claddings of a full cross section) and ring specimens of two sizes were subjected to tensile tests. The experimental results are used to plot hardening curves, which are true stress-strain curves. The set of these curves is employed to plot the desired flow surface of EK-181 steel.
