Drucker Prager model
Cap model

Hallo, everyone,

I am PhD student in material processing. I have a project of using silicon dioxide powder as forming media for tube hydroforming process. I read some literatures about the material model of granular materials. It seems that the Cap model in ABAQUS should be suitable for prescribing the material behavior in FE model. But it is not easy to do the triaxial test for silicon dioxide powder.

Minimum length scale in ABAQUS

Dear all,



This might be a simple question. What is the smallest length scale that can be simulated in ABAQUS. I am trying to run some continuum estimates for particles with dimensions in the nanometer range (10 to 50 nm). Is it possible to specify such length scales in ABAQUS?



Thanks for your insights.

Hi guys,



I'm working on an ABAQUS extension/plug-in of a sort and I'd like to replicate results for a single 4-node plane stress element produced by the ABAQUS incremental/nonlinear static solver.



I assumed the relationship is:

t[K] {Δx} = t+Δt {P} - t{F}



This is how I went to obtain these values:

t [K] - element stiffness - by using *ELEMENT MATRIX OUTPUT

Hi all,

 

I am new to Abaqus and I found the problem I unexpectedly cannot solve.... My case is quite simple- I have 2D frame, part of which is under nonuniform pressure distribution (described by linear function). When I create analytical field referring to previously created local CSYS, apply a load in 'static general' with distribution determined in analytical field and try to run a job, i have a message:

report generation

Hi,

I am performing natural frequency analysis on a cylindrical structure in Abaqus. I am extracting about 80 modes (considering the presence of symmetrical modes). I want to generate a report with all the mode shape patterns and corresponding frequencies listed. Is there any way to do this automatically? Taking Prnt Scrn and generating word document is consuming lot of time and also I have multiple model combinations to do such analysis.

Thank you in advance.
Regards 

Kiran
