about concrete

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

bullwheel

Hi everybody,

I have some problems with the structural analysis of an drive bullwheel on Ansys.

How can I apply the load on the bullwheel groove? 

Tangential (constant) and normal components

 

I was thinking to apply the normal load using a prep>loads>define_loads>apply>FUNCTIONS but I'm not good at this option. Is it necessary to define a particular coordinate system?

spring elements

I am working on the vibratory simulation of engin cooling system. Now
i want to add the component of rubber isolators , the idea is to add
the spring element ,we have tested the dynamic stiffness during range
of 5-100HZ , i konw that in ANSYS we can use the matrix 27 element to define the dynamic stiffness ,but how can i set the values in abaqus or inp files.

Thanks for your helps!

Award

It is my pleasure to announce the launch of the "Eshelby-UH Mechanics Award for Young Faculty". This award will be given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.

Hi.



I want to model cylindrical shell that it's thickness varies from top to bottom with this function







 h=h0(1-ε cos(θ)) or each arbitrary function that is vary from top to bottom.How can I do this? 



 Please help me!!! that for my pleasure to be guided with your comments.
