ABAQUS Modelling of Wrapped Cylinders

Hi all,

I am modelling a cylindrical concrete beam with woven roving glass fabric and I need help on how to model the same.

I have done the analysis of the plain model and validation was also successful, but in case of wrapped member model the results are not acceptable. The maximum strength of the wrapped member is coming out to be similar to the plain analytical model.

I have created two cylindrical sections, one of concrete and the other of the fabric and I have defined a Tie Contact between them. 

Is there any other way I can go to model this.

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,

Spring in Abaqus

Dear all



When i assign the springs between pair points in two
plate over each other, the spring definitely acts in one direction only
(perpendicular to the plates), but they must be assigned in such a way
that the springs work in three orthogonal directions. it is important to
mention that the two plate is fastened using screws, where the spring
has been used for screw.

how can i overcome this problem?

 

Best Regards
