Good day everyone!

I have two questions about concrete modelling in Abaqus.

1. How to create smeared skin reinforcement  -i mean how to assign rebar numbers to elements.

2. in Concrete damage model how to find dilatacion angle (flow angle) using code parameters (i mean tensile strength and others).

Thanks a lot.

Does anyone knows how to export the elements generated in Abaqus-CAE ?

Thanks

Hello,

Recently I faced few questions in a course that I am attending:

1) Outline the salient features of different higher order shell theories.

2)Explain why some shell theories are not suitable as the basis of element formulation.

3) Discuss any limitations of elements being used in relation to their underlying formulation ( e.g use of shallow shell theory or cylindrical shell theory).

Please help me if you know.

I need to simulate a thick tube suffers internal pressure. Assume that there is not deformation in thickness direction.

How to impose the symmetric boundary conditions when I simulate a part 10° of the tube (only 10°, not 90° )?

In Feap 7.5, is there the quadratic hexahedral element (20 nodes)?

Best regards,

NH Nguyen.

Recently, I am trying to build a plastic contact model to describe teh relationship between the plastic deformation and the contact force, which is a crucial point in my work that dealing with the grasp force in robotics. So, anybody has some ideas about this? Actually, I am attempting to find a analytic model

Dear All,

I am modeling rubber seal with hyperelastic material and I am using CAX4R Element for modeling. I achieved contact solution using initial analysis and as an output I got contact pressure and radial and axial displacement of the nodes.

Is there any good reference for creep strength of 304 stainless steel
at 1000C? I am very curious the behavior of such material at extreme
conditions, like creep strength as a function of temp.

Thanks a lot,

Henghua

Hello everyone,

    I am M.Tech student,i am working on Stability of shell Structures. I am in the process of selecting a relevant topic to do my M.Tech Thesis. For almost 2months now, i am searching for a topic which will be new and had not done much in the literature.

    I had seen topics like anisotropic shells, buckling instability, snap-through, cracks in anisotropic cylindrical pressure vessels.

Hi



I am using a FORTRAN FE code for 4 quad elements with a viscoelastic material and with contact analysis. The routine follows a Newton Raphson iteration scheme and which makes the residual zero for convergence. I am using direct sparse matrix solver from the FORTRAN math library.

hello colleagues

I want to do project on

Modeling of Friction Stir Welding (FSW)

Process with SPH........

I am new to this area but i know ls-dyna..if u have any

idea.. sample key files???... about this topic.... pl guide me...

 thanks in advance
