摘要:A new method of constructing yield criterion for thin-walled tube was proposed based on experimental stress and strain parameters under biaxial stress state. For the 6061-O extruded aluminum alloy thin-walled tube,the stress calculation model of thin-walled tube during bulging experiment under biaxial controlled loading was analyzed,and based on this,several flow stress-strain curves of thin-walled tube under different biaxial tensile stress states were obtained by experiment system of tube bulging under biaxial controlled loading. Taking Hill48 model as an example,the yield criterion of thin-walled tube was established based on these flow stress and strain components of thin-walled tube under biaxial tensile stress states. The results show that compared with the yield criterion obtained by traditional method,the yield behavior of thin-walled tube under biaxial stress states is described accurately by the yield criterion established by the experimental stress and strain components under biaxial stress state,and the evolution process of subsequent yield behavior is more accurately characterized.
