Temperature dependence of the thermo-mechanical properties of aluminum

Submitted by omidomid on

I'm looking for the thermo-mechanical properties of aluminum, such as  Young modulus, thermal expansion coefficient, thermal conductivity coefficient and poisson ratio as a function of temperature :

E=E0(1+E1*T+E2*T^2+E3*T^3)  ;  T: temperature in K

Postdoctoral and Graduate Assistant Positions are

immediately available to work on phase-field simulations of phase

transformations and microstructure evolution in metallic alloys or

oxides. Strong background in mechanics and thermodynamics of of solid

microstructures is a plus. If interested, please email a resume to

Several questions for VUMAT

Submitted by meshfreer on

Hi all, I am a new ABAQUS VUMAT user. I am defining the material behavior in stamping of sheet metal through VUMAT. But there are several questions about VUMAT.



(1)accoring to the ABAQUS user manual,for plane stress problem,stressnew(nblock,ndir+nshr), where ndir=3,nshr=1, but in fact,there are 5 stress commponents: sigma_{11},sigma_{22},sigma_{12},sigma_{23},sigma_{31}.

how to match stressnew(*,i)(i=1,2,3,4) with the stress commponents: sigma_{11},sigma_{22},sigma_{12},sigma_{23},sigma_{31}?
