Do you want to learn the boundary element method (BEM) and the latest fast solution methods from the experts around the world? If yes, come and attend the workshop on the BEM in September.
I have done many natural frequency analysis of a cantilevered beam, i want to compare with the theorical solution
How can i calculate the natural frequency of the orthotropic cantilevered beam ?
1. We present an interesting application of ADINA FSI in the study of carpal tunnel syndrome. The analyses involve large deformations and contact of multiple flexible bodies which are immersed in a fluid:

2. Please recall that we offer a very attractive academic package, for research and teaching, for university users. For more information see
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!
