WORKSHOP: Image-based Simulation for Biomechanics, Materials Applications, and Reverse Engineering

This workshop is aimed at those interested in 3D reconstruction from radiology images, and in using 3D image data (as obtained from CT, Micro-CT, MRI and Ultrasound) to generate Rapid Prototyping, CAD, and Finite Element models.

Participants will learn:
•    how to generate computer models from your 3D image data
•    how to import and position CAD files in the image data
•    how to integrate with CAD Software as well as FE solvers such as Ansys, Abaqus, Comsol, LS-Dyna, etc.

I am looking for a postdoctoral position. I have expeience in finite element modeling and laboratory measurements of ultrasonic waves in ferroelectric and piezoelectric plates, piezoelectric transducers and actuators, MEMs. Also worked in the field of computational electromagnetics. Please look at the attached resume.

Materialise and Dassault Systemes Simulia Benelux are pleased to announce their co-organized Medical Engineering Seminar which will take place on 4 October 2011, at the Materialise HQ in Leuven, Belgium. The Medical Engineering Seminar is a meeting for and by users and aims to bring together biomechanical engineers currently working, or interested in patient-realistic finite element modeling.

Hello,

I was wondering if any commercially available FEA softwares allow multi time step analysis. 

By multi time step I mean being able to integrate different regions of a mesh with different time steps. 

Say there is a cantilever beam, I wish to use a different time step on the fixed end half of the beam and a different time step on the free end half of the beam. 

Please let me know if there is an application/software that allows me to select different time steps in different regions of the mesh. 

Thank you.

In general for incremental plasticity problems it is well known that one has to use an iteration scheme (Newton-Raphson, modified Newton-Raphson or Quassi Newton etc.) in order to achieve a converged solution for finite element equations. Is it also neccessary to have an iteration scheme for an incremental viscoplastic problems ? I am also attaching a paper where the authors have implemented an equilibrium correction scheme in the principle of virtual work, which is supposed to ensure convergence. I am not able to comprehend how it takes care of the convergence without any iterations. Any help would be highly appreciated.

Thanks

Packaging mechanical engineers conduct simulation of electronic packages
to optimize package design for compatibility with assembly processes
and for reliable operation in end user systems such as servers, game
consoles and network switches. Simulation is conducted using commercial
finite element software such as ANSYS or ABAQUS to predict package
component stresses and strains. Simulations are verified by measurements
of warpage and stresses / strains in the packages using Digital image
contrast, strain gages, capacitance meters, etc. Package material
properties such as coefficient of thermal expansion, Poisson ratio and
modulus that are required for simulation are measured using specialized
mechanical equipment. Thus, familiarity with numerical simulation

Hi

Dominique Chapelle and Klaus-Jürgen Bathe

Can you define FEM in one line?

If yes, what would it be? And, in that case, permit me a second question: How?

...Really interested in knowing what the members of this community think (of this matter), if they do...

All,

Could anyone recommend courses, online materials or text books that
would be suitable for teaching the finite element method to someone with
a non-engineering background. This request is on behalf of an MD
student wishing to use the FEM for modelling the wrist. We're initially
looking for introductory materials.

Best regards

Lee

Authors welcome any comments for future studies!

In Abaqus .inp or Abaqus/CAE, are there mesh generation commands similar to ANSYS commands FILL, NGEN, and EGEN used to geneate nodes (between keypoints) and elements ?

Hi,

I would like to write a simple subroutine to solve diffusion equation d(ro)/dt = k∇2(ro). using finite element method.

Any suggestions ?

Thanks,

Ayoub 

i am a resercher working in mechanical engineering department in NIT,rourkela,INDIA.My present research On ultrasonic turning.I am using ansys for finite element modeling of ultrasonic turning.if any one have working on that field ,pls give some tutorial like orthogonal cutting using ansys and many more.

Would like to hear your expertise/user/non-expert/sceptic comments on XFEM. Here are some of the challenges. Would like to hear your relections.

1. Can XFEM be utilized in characterizing Failure rather than Fracture?

2. What sort of challenges XFEM still have with respect to Fracture Mechanics?

3. How the Fracture mechanics benefit the industry, from the perspective of strcutural integrity?

4. Failue investigations vs. Fracture investigations: benefit to industry?

5. Academist vs Engineer: Perspective on XFEM

If possible, please vindicate your justifications with any relevant literature. Would like to see where and how XFEM is evolving.

Hi,

For a personal project I'd like to find a free program that lets me see what happens when I take a beach ball and apply greater and greater weight on it.  I'm specifically interested in the deformation of the ball, and the stresses in the material.

I'd like to be able to input these variables: radius of the ball, thickness of the material used, weight of the weight, Young's modulus in machine / tranverse direction (elongation in machine / tranverse direction), initial internal gas pressure of the ball, (gas properties of the air inside the balloon).
