Importing Patran neutral file in to Ansys
I imported the Patran neutral file (with *.out) in to Ansys(for a plate with a hole which was generated in the IDL and was imported in to the Patran) . but just the geometry of plate imported and i had not any elements, nodes (any mesh), and it reported in the Ansys. I also tried "import mesh " and nothing happend. could you please let me know what should I do?
How to choose what kind of element for particular problem (2D plane stress element or 3D solid element)?
Dear all,
I would like to ask expert FEM users that how can we choose what kind of element for particular problem? Such as a plate (thickness t = 2.5 mm, W = 15 mm, L = 64 mm) subjected to axial tensile loading of cyclic loading, I should choose 2D plane stress element or 3D solid element?
It is really appreciated for all suggestions.
Kind regards,
Anh
duplex slip
Hi, can anyone tell me if it is possible for duplex slip of two diferent systems result in one single slip direction?
Thanks
Ansys - Concrete nonlinear beam
Hello,
I have to model with the Ansys software a beam in concrete material. It must be non linear.
In materials properties, I can choose Materials models - Structural - nonlinear - inelastic - non metal plasticity - concrete.
I put the Elastic Modulus, the Poisson´ratio, the uniaxial cracking stress and the uniaxial crushing stress. But I don´t know how I can enter the values of the strain at fc (compressive cylinder strength) and the value of the fracture energy.
comment
I have glanced through both messages: "About: why....." and "The reasons of...." And was surprised: there are hundreds of readers but no one comments. What happened? Are there a lot of cheap energy - isn't a problem? And good diamonds aren't interesting?
May be this magazine read only simple people, and serious scientists and engineers are ignoring it?
It's a pity; this topics aren't empty; if the author writes nonsense, clever people must show on it.
VUMAT Drucker Prager Abaqus
Hello !
I am looking for a vumat in which the drucker prager criterion is implemented. Does anyone have this subroutine ?
Is it for you to send me a copy ?
Best regards

FEM Is Not a Local Method (and It Isn't Global Either)
In the literature, FEM has sometimes been characterized as a local approach, but IMO this needs to be corrected.
The piecewise continuous trial-functions of FEM can be looked at from two different viewpoints:
problem with meshing
hi friend
iam new to ABAQUS and
i am modeling a sample plate in Abaqus with a crack and partitioning the
region at crack tip, but im getting an error such as "24 elements are
within a contour region. The elements are identified in element set
ErrElemIncorrContInteg".
Iam also attaching the file that i have modelled. please anybody help me in solving the problem
Abaqus CAE
I intend to create a
composite model, containing a cylindrical fiber surrounded by a cube, by Abaqus CAE v 6.7-1. I create
two separet parts, one for the cube and the other one for the cylinder. Then, I
cut the cube by the fiber; the third part (lets say the cut part) is created
automatically. Now, I need to mesh the parts and merge them.
