I am modeling a truss in fire conditions, using ISO 835 fire for it. Now I have included some imperfections on the braces(L/1000) and I would like to know how to run this type of analysis(RIKS)
I used normally two steps, one to define the load on my truss and the second to import the temperatures as a predefined field. At this moment I do not know ho to modify my model steps in order to reach the solution. My temperature analysis takes 30 min and I cannot add time to a riks analysis
I am a bit lost, If someone could help me, I would be grateful to him/her.
In this project, Simpleware's image processing and mesh generation software was used to complete an ancient geological process through new technology. The goal of the project was to create a pseudomorph, an object that maintains an original shape over time while changing its inner materiality.
The pseudomorph in this project represented a snail that had become fossilised as an air void within the Jurassic Coast’s rockbed over millions of years. High-powered CT technology and Simpleware software was used to visualise the microstructure of Portland roach stone and to extract a mesh of the air void suitable for 3D printing as a new object.

Je cherche comment nous pouvons faire homogénéisation sur ABAQUS.
merci à l'avance.
Is there anybody use PATRAN and NASTRAN to simulate rotor-bearing sysytem.
After modeling the shat and meshing it, I don't know which element type can be used to
analysis the bearing than contain cross stiffness and damping coefficients.
The following is an exmple:
I'm trying to model with abaqus a SSI between a axisymmetric concrete shell and soil (parameters are not too important right now). The main problem with the interaction is that in the edge area of the shell it is in tension and thus the foundation will rice from the soil in these areas. My question is what method would be the best to model this kind of behavior. I know that using spring elements the nonlinear behavior cannot be modeled. I read from the user manual that connectors could be used to model the nonlinear interaction between two nodes. Could it be possible to make a reference point for each node and connect the nodes to the reference points? Also the stiffness of the connector might be hard to determine in axisymmetric model...

Iwant to model progressive impact damage problem in Abaqus. I know the theory, but I don't know how to use Abaqus to modeling damage. is there any example, tutoial or etc to help me?
Dear imechanica users,
I have decided to learn how to use .ses and .pcl files in Patran to simplify repeatable operations.
In my problem, I would like to consider several beams of the same length, loading/BC conditions etc. but with different cross-section dimensions.
In order to make my calculations fully automatic, I have parametrized both width and height of the cross sections (as REAL a,b) and created nested FOR loops to obtain 20 different designs.
I would be grateful for answers on these questions:
This preliminary release is limited to linear elastic material, axisymmetric geometry, spherical rigid indenter, and various boundary conditions.
We are currently working on adding viscoelasticity (Prony series), cylindrical and conical rigid indenters, and loading functions.
Could you please explain to me how to model a crack in ANSYS APDL and obtain its stress intensity factor...
I have an eigenvalue solver, subspace iteration, that can get only positive eigenvalues. I have a problem (K - lambda M)u=0 that has pairs of eigenvalues +/- lambda. How can I transform the eigenvalue problem for the solver to search for lambda^2 rather than lambda?
hi,,,,,,,,,,i am doing project on viscoelastic sandwich beam in ansys can any1 give idea how to model ,assign properties ,which element,,,,,,i need to choose if any references /tuturial/copy,,let me know it will be helpful,,,,,,,,,,,,,,for me...............email@example.com
I am getting displacement and force both zero. I am attaching .cae file please have a look where i am making mistakes.
New research is emerging out of a project where Ohio State University used our software to reconstruct the anatomy of an ant neck. In this project, micro-CT scans of an ant neck were reconstructed using Simpleware software and exported as a mesh for analysis in Abaqus.
Simulations in Abaqus identified where stress concentrations tend to take place for ants' necks, providing insight into how they are able to support large weights. This research has created the potential for developing micro-robots capable of handling similar loads, as well as other ant-inspired designs for space engineering.
does anyone know, if it is possible to transfer a FE-Model from Abaqus to LsDyna? I build up the model with Abaqus Cae, so I can take either the *.cae or the *.inp file.
Thanks for your answers, Lena
May I know how do I export meshing from abaqus to nastran? is it possible?
I am new to this iMechanica. I am facing difficulty with simulating Groove noise in abaqus.
Can somebody help me out.
I am currently working on a project which needs mass-spring model. Previously I use MATLAB to implement 1D and 2D system, and I want to model 3D system by ABAQUS now. I am just starting to learn ABAQUS, it seems like there is not much tutorial or example about this kind of model.
I try to search in ABAQUS User's Manual, and get to know I can use the spring element. But how can I model the mass? I notice there are analytical rigid and discrete rigid when making a part, is this used to implement the mass? Since I can only import one discrete rigid once, how can I construct a big system?
Thanks a lot.

Engineers are under increasing pressure to improve and extend the operating life of structural components. Abaqus FEA provides proven robust capabilities for modeling bulk fracture and crack propagation in composites.
This live eSeminar will focus on basic concepts of extended Finite Element Method (XFEM) in Abaqus, damage modeling and the creation of an XFEM fracture model. There will also be a short hands-on demonstration using Abaqus 6.13.
Advantages of using XFEM in Abaqus include:
