Frontiers of Mechanical Engineering 2013, Volume 8, Issue 2,   Pages 181-186 doi: 10.1007/s11465-013-0257-7

Abstract:

This paper demonstrates the application of a new multiaxial creep damage model developed by authorsusing stress traixiality to predict the failure time of a component made of 0.5%Cr-0.5%Mo-0.25%V lowThe model employs strain energy density and assumes that the uniaxial strain energy density of a componentto a function of stress trixiality which is a ratio of mean stress to equivalent stress.The predicted failure times by the model are compared with the experimental results.

Frontiers of Structural and Civil Engineering 2018, Volume 12, Issue 1,   Pages 148-162 doi: 10.1007/s11709-016-0375-5

Abstract: Finite element modeling of the HSS braces that utilizes the true stress-strain curves produces hysteresisTrue stress-strain curves are obtained from coupon tests or stub-column tests while utilizing an exponentialIn the current study, the true stress-strain curves are directly obtained from tests on stub-columnsTwo experimental tests (Shaback 2001 and Haddad 2004) were used to validate the model.Results indicate that the stress-strain curves for these braces are not unique.
