Cyclic plasticity of Cu63Zn37 Alloy under mean stress
Pečálková, L. ; Kunz, Ludvík ; Borůvka, O.
Continuous hardening is a typical feature of the cyclic plastic behavior of α-brass loaded with a tension mean stress. Cyclic stress-strain curves are shifted by an increasing tension mean stress to lower values of plastic strain amplitudes. An increasing mean stress results in increasing cyclic strain hardening exponent.
Influence of pre-strain on cyclic creep of copper
Pantělejev, Libor ; Kunz, Ludvík
Cyclic stress component can either accelerate of decelerate the cyclic creep of copper loaded with a high mean stress, according to details of the start-up procedure of a fatigue test.
