Assigning two material behavioour to a beam

Submitted by manoochehr on Sun, 03/15/2009 - 23:52

Hi Everyone,

I am quite new to this blog, and I enjoy of studying your comments. I have a problem in ABAQUS/CAE. I am trying to model a wood beam that has two beahviour in tension and compression. Elasto-Plastic behaviour in tension and in compression Elsto-Brittle behaviour. Is there any way to model this material in ABAQUS. My problem mainly comes back to this case that we can not assign to a beam two materail behaviour simultanously.

Thank you for your reply.

Element free Galerkin method

I would like to know whether any works have been done in EFGM which suggest the best points in the domain where the stresses have to be computed, like in FEM we do have Gauss points which give minimum error for secondary variables. So can any one please suggest some references in this regard?

Dear Sir/Madam,

I have recently (Fall–08) completed my Ph.D. in mechanical engineering with specialization in general areas of nonlinear structural dynamics and model order reduction. If any Prof. or research organization has an opening for a postdoc position in the areas of my technical expertise, please let me know at kumarnish [at] hotmail.com (kumarnish[at]hotmail[dot]com).

Thanks,

Finite Deformation: Special Cases

Submitted by Zhigang Suo on Sat, 03/14/2009 - 23:28

The notes on finite deformation have been divided into two parts: special cases and general theory (node/538). In class I start with special cases, and then sketch the general theory. But the two parts can be read in any order.

Abaqus embedded truss problem

Submitted by hmousad on Sat, 03/14/2009 - 20:16

Hello,

I'm trying to model a hollow pipe that have inside a 3D truss element. I've embedded the truss upper part in that cube shown in the picture attached.

The problem is when I apply lateral force what happens is that the bar just don't follow the pipe in its motion. The last mesh element in the embedded part isn't attached anymore to the upper cube.

Dear Friends,

I am doing M.Tech Structural Engineering at NIT, Trichy. Now i am working on modeling of composite structure in ANSYS. I need some idea about that.

ANSYS - Coordinate system following a tangent of a curve

Submitted by Goran Visnjic on Fri, 03/13/2009 - 19:58

Hello everyone,

I'm trying to analyze a composite shell of a light aircraft fuselage. There are some layers - UD reinforcements in the shell of fuselage, that should follow certain path on the shell. So the layer coordinate system should rotate with the tangent of path - 3D curve. I saw a picture in a science paper, where micromechanics of a fabric lamina was analyzed in ANSYS. The coordinate system was following a centerline of a fiber.

Can anyone give me an advice how to do this? Thank you in advance.

Greetings,

Goran
