mechanician

There are six distinguished biophysicist in cell mechanics field (their research interests cover much broader areas) and the abbreviations of their first names are either C or D. They are Dr. David Weitz (Harvard U.), Dr. Christopher Chen (U. Penn.), Dr. Dennis Discher (U. Penn.), Dr. Denis Wirtz (JHU), Dr. Douglas Robinson (JHU), and Dr. Daniel Fletcher (U.C. Berkeley). These six scientists use both experimental and theoretical approaches to investigate the biological responses of proteins and cells to mechanical stimuli, such as forces and geometrical constraints. Their research extends from molecular scale to cellular level to tissue level.

Hi.

I'm working  with the element link8 (Ansys 12.1) and I have to
introduced the tensile curve and compression curve, but I don't know,
How I have to introduced its???

I have worked with the comands: TB: aniso, miso,..., I think the best
option is: TB, user, but How I have to introduced the values of tensile
and compression curve?, when this are different.

 File attachment is the tensile and compression curve to introduce

Thank you, Toni 

Hello,

I am working in a fluid mechanics theme. Do anybody now something about the Radial Reynolds Number? 

Thank you. 

Could someone explain me what do the curvature tensor mean at surface structures?



THX for the help!

DEAR everyone :

    I want to  combine XFEM and UMAT(about concrete) in ABAQUS,I have some questions about this ,concrete is a Special materials and I have the Constitutive equation about concrete ;Can I use the new constitutive equation and  simulate mixed CONCRETE cracking by XFEM(UEL_XFEM) in ABAQUS,how to combine UEL and UMAT in abaqus, thanks in advance,or you can Recommend  some relative infomation for me
