We are looking at implementing a non-linear model with friction, and at least in the first place for statics. We haven't found much in the literature on non-linear models for friction in FE.

 Anyone any advice on key papers to read ?

Thanks,

Hi all

I want to do a transient analysis in ANSYS or ABAQUS software.

 but the material has a frequency dependent damping. 

how can I simulate this property in FEM software?

Dear all,

I am considering using OpenSees software in plane strain SSI analysis
under cyclic loading. I have understood, roughly, how the structure of
the input file and the Tcl scripting language work. Nevertheless, I
would like to know; I understand that to model a rigid body, in
OpenSees, you can tie the horizontal and vertical displacements of the
nodes of the rigid entity. Is there any other way? Or did I
misunderstood?

Hi

I have some problems in using  heat effect and temprature gradiant in Sanders shell theory

I will be very appreciated if anyone can help me

thanks a lot 

Hi Every body,

I know that the crack propagation energy release rate G is by defination the release of elastic energy and potential energy of loads per unit area of crack extension and for a linear body loaded by a single load P is given by :

G=P^2/(2b)*dc/da

Any body know if instead of load P, moment M is being used what would be formulation?

I really need this one

Thank you,

Why the elastomers are giving large actuation,what is the reason behind it

Hi,
