PROGRESSIVE DAMAGE AND FAILURE ABAQUS / EPOXY RESINS

Hi everybody,

 have you ever tried to model the damage behaviour of a material using the theory of progressive damage and failure

for ductile metals implemeted in Abaqus for continuum elements?

If so, do you think it is possible to use the same theory to model the damage behaviour of an epoxy resin?

Are there any articles in which this has been done? Could you please suggest me some articles to read?

 Thank you very much.

Regards,

 Cecilia 

How to apply pressure on perticular side of the shell element

If a pressure is to be applied on one of the sides of the shell element (not on the mid surface) in ansys, how to do it? And if the pressure ie acting on both the sides of the geometry, then how to take care of it when shell element is being used?

Bimaterial interface modelling using ABAQUS

Hii all,

How can we model a bi-material interface using abaqus. 

Aircraft Wing Dynamics

Choose a channel featured in the header of iMechanica: 

Hello,

I am looking for any resource where I can get some data regarding the average force and its time variation with which the wind applies force onto an aircraft body especially the wing. To reframe the question in a better way: can anyone recommend a resource that has data about the wind velocity profile around the aircraft (especially the wings) or pressure/shear force profile on the boundary of the aircraft (especially the wings) during various phases in its flight. 

If periodic boundary conditions do not respect stress continuity at the boundary....

Hi everybody,

have you ever tried to implement in Abaqus periodic boundary conditions?

I am doing this. Particularly, I am applying PBC to unit cells constituted of a clay particle in an epoxy matrix.

When I apply PBC in case of transverse shear, I have convergence problems using Abaqus standard,

so I have to use an algorithm of stabilization but because of this one

I have to renounce to the stress continuity between opposite boundaries of the unit cell.

Do you think this is normal or I am doing some mistakes?

How are Compression Modulus and Tensile Modulus related to Lame` constants?

Choose a channel featured in the header of iMechanica: 

Hello everyone

I have a material with a compression modulus and tensile modulus along with Poisson's ratio. Are compression modulus and tensile modulus related to the Lame` constants? Or does this material fall under 'cubic symmetry' which needs three elastic constants? In that case, how are they related to the elastic coefficients (C12, C44 or C11)?

I need to incorporate these material properties in ABAQUS. How do I model this material in ABAQUS?

Any lead on this problem is appreciated. Thanks a lot.

Can I retrive strain increment in ABAQUS with python?

Choose a channel featured in the header of iMechanica: 

Dear all,

I just finished extrusion process simulation in ABAQUS with the input of stress-strain data. Now I want to retrive the strain increment of certain element during each deformation increment. Surely one can write straininc to a *.txt file when simulating with VUMAT. But the simulation of extrusion will be extremely slow with VUMAT. So How can I get the strain increment when simulating with the input of stress-strain data? 

Best regards,

ANSYS VISCOELASTIC MODELING

Choose a channel featured in the header of iMechanica: 

Hi,

 I am trying to model a sheet of Poly Vinyl Butryl (PVB), which is a viscoelastic material in ANSYS. I have all the regular properties like elastic, shear and bulk modulus, poisson ratio, denstiy and damping factor. I also have a stress- strain curve of PVB. With all this data, is it possible for me to find the various constants in the viscoelastic models using ANSYS?

 Thanks

How to define Pre-Strain (or Pre-Tension) in ABAQUS?

Hi,

I want to medel an overhead line conductor in Abaqus. As you know, the suspended cable has a parapolic (or catenary) profile under its weight. There is a pre-tension (or pre-strain in elastic region) on the cable due to its weight.

I found in the help of Abaqus that I can use the "Bolt load" option to define the pre-tension, but it does not work for my model. Because my model doesn't have surface to choose for this type of load (it's a 2D wire part).

Would you please let me know how can I define this pre-tension (or pre-strain) in my model?
