Convergence of Stress Value Near a Sharp Notch in ANSYS or ABAQUS

Submitted by ali_mechanic_64 on

Dear All

I'm working on my thesis and in a part of it, I have to determine the stress around a sharp v-notch specially on the tip of it. the model is so simple(a rectangular plate with a v-notch on on the left side of it) and the load is tensile. But after solving the problem with both ANSYS & ABAQUS I realized the finer meshes,the greater stress on the tip of notch. I tried p-element method,but by using maximum level of p-element(that is 8) and fine meshes I couldn't reach to convergence again. I'm so confused and I really need help.

thanx.

Ansys Analysis of Prestressed Concrete Columns

Submitted by Renato FAU on
research

Hi,

Has anyone or can anyone help me model a prestressed concrete column on Ansys?

I have to model several different prestressed concrete columns to compare to an actual experimental result. I am just getting my feet wet with ansys and any help will be greatly appreciated.

Thanks!!! 

Wavelengths of surface features

Roughness
wavelengths

I am working on the surface features of steel . I understand that surface features are broken down into various wavelengths and represented as Wa to We (0.1mm to 30mm wavelengths). Could some guide me to a reference which shows how to go about this process from the raw surface profile data ? Possibly, it involves Fourier Transforms, but I need a basic reference which shows how it is done .

 

Thanks!

Learn Engineering on Anatomy in an Innovation Course

Submitted by Mimics on
conference
biomechanics
medical image processing 3D FEA CFD CAD RP mesh

At least 25 Innovation Courses will be organized all over the world by Materialise.
The Innovation Course is an accessible, 2-day, hands-on training in the Mimics Innovation Suite in which you start with medical image data, create accurate 3D models and learn to; e.g. do 3D measurements and analyses, prepare for FEA and design patient-specific implants.

Join us at a location of your choice to see how powerful, yet how easy it can be to preform engineering operations on anatomical data.
