Ansys - Concrete nonlinear beam

Submitted by Guillaume Gondre on

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.

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.

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

Submitted by hadi on
software

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. 

SciTopics launched by Elsevier

Last fall, Elsevier launched SciTopics. It is a web site devoted to providing research summaries of current topics by experts, allowing for public interaction through comments.  Anyone can become a member and post comments, or request to author a page. 

 

 In many ways, it resembles iMechanica.  Authors pen SciTopic pages in their area of expertise.  SciTopics leverages Scirus , which is Elsevier's free, science-specific search engine.

ABAQUS - i need help to define my boundary condition/loads etc. Please help.

ABAQUS/CAE

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,

arr
