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.

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.

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

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

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. 

Hi All,

 I'm really new on abaqus and currently having tremendous problem with it. Could anyone help with it? I'm trying to simulate a thin sheet clamped by rigid jaws and moves it onto designated position. Could anyone advice me on how to its boundary condition and so on.. ANy advice is welcomed. I'm really2 desperate.

Thanks in advance,

As a follow-up to the discussion here, I am attaching a PUFE homework that I have assigned in 2006 and 2008 when I have offered a meshfree/pufe course. This might be of some help to those who have an interest in partition-of-unity enriched finite element methods.
