Hello all expertise,

 I have some inquiries that need to clear...may I know about HETVAL Subroutine from TRAST? what are the significant of this subroutine to the programming? and where did i can get the subroutine trast7_tv?How does it works actually?....

I hope somebody willing to help me..thank you in advance..

We are opening one or two Assistant Professor positions at the Division of Computational Mechanics, Ton Duc Thang University, Vietnam led by Prof. Hung Nguyen-Xuan and Dr. Trung Nguyen-Thoi. The candidates who hold a PhD degree on Mechanical Engineering, Civil Engineering or Computational Engineering are expected to work on some national projects on the field of computational fluid dynamics (CFD) and enhance the on-going research activities of the group.

Information on the Ton Duc Thang university can be found here

If you are a master student and would like
to do your master thesis, there is an opportunity to do it at Bosch in
Stuttgart, Germany. The grant will be given for 6 months and can be extended to
6 more months ( 6 months internship plus six months master thesis.)

For more information regarding the grant and
the position please see below job description or contact me.

Job description: 

I was pointed to this article on an emerging model for education/universities, which I found to be a good read.  

Pordon me if i couldn't reach my intention correctly. 

You know that I have the functional dependence. For every elastic plastic property I have its termal function.

for example:

E=E(T), NU=NU(T), Syield=Syield(T).

But my question is that is it correct to define:

T=temp 

and then

write Those function as props 

Props(1)=E(T), etc.

or I ought to dedine the properties at several temprature separately and then define the strains and stresses respectively??

for example:

at T=T0

Dear Colleague

i want to model the piezoelectric material in abaqus, i want to analysis the stress and fracture but i have a lots of problem with this material, can you help me in this case please?! thanks in advance.

my email: mahyar.iii [at] gmail.com 

Dear ALL

I have this PDF and I have some information at this coding but have not information about the temprature dependent material properties.

what can I do??

sorry for that

For example see this function:

E(T)=E0*T^2+A*T+ ....

What can I define this type of Function?? 

Is my statement true? Can I do alike nonisotermal behaviour of the material???

 Please help me 

 Thanks so much

Regards 

Dear All redears

Thanks for helping me about the defenition of solution dipendent satet variables.

I have another question and is that what can I do, if I want to define temperature dependent material propertiies at UMAT?

is it true to define temprature as a propertiy at the start and end od incerement and compute the propertiy at both cases?? I mean at end and start of it??

To clear the propblem for example i have this type of material peroperty:

E=E(T), NU=NU(T)

for example E and Nu are function of temprature.
