Testing standard impact test

Submitted by Anna Dolgran on

Ask iMechanica

Dear imechanicans,

 

I am starting to do charpy test on a fiber composite and I am wondering about the testing standards. (because I dont wont to choose a wrong geometrie).

The problem is: the given sample is a hollow tube with a given wall thickness.

 Do you have any ideas on which testing standrads my analysis should be based on?

Or what should I pay attention? (because it is not a standard sample)?

 

THANKS

Good day everyone,

I'm new to iMechanica and look forward to getting to know everyone here.

I'm currently doing analysis of interlaminar crack growth in fibre-reinforced composite by Extended Finite Element Method (XFEM) using Abaqus. I'm a new Abaqus user and therefore I have to familiarise myself by constructing random 2D and 3D models with isotropic materials before jumping onto anisotropic.

    I'm programming a finite element program to analyze the force of submarine pipeline.When the pipeline is lifted highly from seabed，it is a large deformation problem.

    Is there any open soure  to solve the problem?

    Give me some advices.

    Thanks a lot!

Fluid-structure Interactions

For those of you looking for FSI simulation on Abaqus platform, recently Simulia has announced the new features in release 6.10, which introduces the capability for performing Computational Fluid Dynamics (CFD) simulation.
So it enables users to perform coupled physics simulations with
Abaqus/Standard and Abaqus/Explicit, such as fluid-structure
interaction between human tissue, a medical device, and fluid flow, more information:
