Hi I have long been looking for a clear way of defining stress intensity factors. Apart from the usual bookinsh definitions such as "strength of singularity" "state of stress". Of course I could convince myself by relating SIF with Strain Energy Release Rate (G) as 'G' has a more convincing physical meaning explained through the creating of new surfaces. This kind of gives the feeling that 'K' is a derived quantity in the field of fracture mechanics.

So is there a better way of explaining SIF without having to go through 'G'.

Thanks and Regards

Hi Guys,

Hi all, 

I am quite new to Abaqus. I would be grateful if anyone can answer my question. I am simulating rock drilling. I want my rock mesh size around the bit dynamically become fine. Is it available in mesh adaptivity? If so, It would be great to let me know with details.

Best regards,

Nina

I am new to abaqus and currently working in Abaqus 2016

I am getting the error 5 unconnected regions in abaqus. I have checked thoroughly all the interefaces and boundary conditions but I am not able to sort out this problem. Also I am getting Displacment increment is too big for contact. The job is getting aborted eventually.

I have attached images of the model.

Hello. I want to read .odb file in ABAQUS to extract nodal data. Please, guide me regarding it. I am waiting for some useful comments

Hello. I want to extract the nodal data from Abaqus. Please, guide me regarding it. Moreover, if i would need some Python script how can i run that script in ABAQUS. Waiting for some useful comments 

Namaste from India.Jay Naik here. I am Post graduation Student doing Specialization in Machine Design.I am Doing My project in Master in area of" Design of storage tank" in One of the reputed company in Static Equipment Design.Any Idea on which Software(Fea or failure analysis) Design of storage tank is carried out?I have heard about AMETank and Ansys.

Secondly i am carrying out Literature review Present days.reading API 650 and other standards.Suggestion requires in this area.

Please guide me in proper manner.in which way i should carry out the project in systematic way.

Hello experts, I am trying to model the response (damage+plasticity) and compare with commercial FE codes. I chose to follow explicit scheme and compare with available implicit solution. Attached image shows the comparison between implicit (commerical FE software) and explicit (my Python program).

 As it can be observed, near the failure, i.e. applied strain > 0.05, there is a noise in the explicit solution. When I decrease the time step, the noise infact decreases.

(a) Is this noise is a result of explicit procedure ? or some thing wrong with my algorithm ?

Dear all,

Do you know of any source that can provide appropriate values for maximum principal stress (Maxps) Damage together with the damage evolution (Displacement at Failure) for steel structures material?

Thanks a lot
