The Research and Computer Aided Engineering group at Carrollton Technology Center of Halliburton is looking for an expert FEA analyst at principal engineer level. This position requires
1) Extensive experience with nonlinear finite element analysis and fundamental understanding and knowledge of Solid Mechanics.
Ice or hail impact is an important design consideration in the aviation, energy, and astronautics industries. Physical testing of impact scenarios can be expensive and impractical. Numerical simulations provide cost effective and convenient tools for including hail impact scenarios in the design process.
Numerically simulating high speed ice or hail impact is challenging because of the extreme deformation, fragmentation, contact, and material model complexity.
I hape a relatively simple question. I am trying to set a maxmimum time step for a job by the lines:
*Static, allsdtol=0, continue=NO
0.05, 1., 1e-25, 0.05
so I believe the maximum time step should be 0.05 giving me a minimum of 20 increments in the step in total. However the STA file below shows that the job starts at 0.05 and the appears to ignore the maximum time step command. Can anyone tell me why this occurs?

SUMMARY OF JOB INFORMATION:
Does anybody how we can put a loop (for example while loop) inside a .psf (parametric study) file in abaqus?
For example a loop on all the increments we want to get a field variable output. Take a look at the following code:
I am doing an explicit analysis, i am trying to model a woven fabric structure. I have to pre-stress the fabric so i have used this option.
I have two questions about abaqus *.inp files.
first of all, as you may know, users are capable of running these type of example files through this way:
File> Import> Model...> SIMULIA>documentation>docs> v6.12> books> eif> *.inp
but when i run each of them (for instance Projectile impacting eroding plate: pl3d_erode_ccs.inp) , two important question marks above them will arised.
first, there isn't any geometry for parts and insted of that you see the term "orphan mesh" there. how we can extract a real geometry from an orphan mesh?
Thank you for your reply. I know but I was wondering if it is possible to omit them manually.
One more question, I figured that using *MATRIX GENERATE, one could get the global stiffness, mass or load matrix in a ".mtx" file. But I am wondering why I can't get the file after the run.
Here is the keywords:
As we know, Abaqus/(v)umat provides the temperatures at each material point at the end of the increment, but in a thermo-mechanical problem, the heat induced by plastic deformation is unknown before the plastic strain is calculated. So, How the temperatures at material points in abaqus are updated?
Thanks in advance.
I am modelling an inflated sphere. The sphere is composed off two circular planar membranes joined together at the boundries.
I have modelled the inside of the sphere as a fluid cavity and will inflate it to its threshold limit.
I have achieved this by using the fluid cavity and fluid inflator method but for some reason when I run my input file I receive the following message:
The latest issue of SIMULIA Community News takes a look at how engineers in the industrial equipment industry are using realistic simulation solutions to optimize performance, evaluate designs, and further their understanding of the environments they work in. Additionally, see how Mazda balances performance and weight in a steel car body and NSE Composites validates their sweep-twist wind turbine blade design that captures 12% more energy.
I am modelling a Piezo Beam 2D and 3D, i have no problem with 3D when i want to apply voltage load, But in 2D, when i apply load i Dont get any results in case of stress and strain Also when i apply pressure to beam, i Must get Voltage in Piezo but nothing happend, PLEASE HELP ME IN THIS CASE; THANKS ALOT
I'm using Abaqus in analysis of random vibration fatigue. I linked abaqus with fe-safe to calculate the fatigue life. Fe-safe didn't recognize the random load comming from Abaqus correctly, althghou it already recognize the cyclic(normal) load crrectly in one of the tutorial's attached example.
Do any body know how to solve this issue?
The reliability of a gas or steam turbine is strongly
dependent on the blade structural design.
Turbine blades are subjected
to very strenuous environments such as high temperatures, high stresses, and a
potentially high vibration environment. To avoid blade failures, they must be
designed to withstand these conditions.
There is a video on YouTube now of a cat using Abaqus...more specifically, the Abaqus Knee Simulator (Abaqus 6.12 release). Hope it makes you laugh:
Have a great week!
I want to start a dynamic calculation in Abaqus in which, for every node, I specify the displacements, velocities and accelerations. I know that by the *IMPORT command, I can start a calculation with a deformed mesh, and that the velocities can be defined by in the *INITIAL CONDITIONS, but how to deal with non zero user defined accelerations? Have any body did that? Is it possible with a subroutine?
Thanks for any help
I build a water inject model with COH3D8RP element, in the simulation, I can get the pore pressure value around the cohesive element, but I can't the value inside the cohesive element. the pore pressure changed around the cohesive element because of the pressure inside the cohesive element changes, however, I can't get the value of pressure inside the cohesive element.
I am trying to perform simulation of Crushable Foam Plasticity model. However, I am getting convergence error
***NOTE: THE SOLUTION APPEARS TO BE DIVERGING. CONVERGENCE IS JUDGED UNLIKELY.
***ERROR: TOO MANY ATTEMPTS MADE FOR THIS INCREMENT
Can someone please help. I have attached the image of Abaqus input data.
Thanks a lot in Advance.
I am a beginer in using Abaqus. I am going to model a nothed specimen subjected to cyclic loads, to investigate the stress/strain distribution and so on. I would appreciate if you guide me.
In this paper, a correlation between simulation and a full crash test is presented. In order to achieve good agreement in the correlation, several Abaqus analysis techniques are evaluated.
Traction Prediction of a Smooth Rigid Wheel in Soil using Coupled Eulerian-Lagrangian Analysis - 2012Submitted by SIMULIA on Mon, 2012-09-24 14:50.
The approach to modeling soil is validated by comparing predicted traction of a trolling rigid wheel to measured traction test date available in the literature. Comparison of the measured and predicted traction force shows that this approach is reasonable for predictin traction in soil.
This paper presents an automated approach to extract strains of aircraft structural models from widely used CAD and FE environments. The developed approach has been implemented as an integrated tool in widely used CATIA V5 and Abaqus environment. The integrated tool is a quick inexpensive and effecive technique for predicting structural strains.
