Submitted by LeCanh on

Dear Colleagues,

We are inviting you to submit abstracts on ICCM2015, Auckland, New Zealand: 

MS-008 Computational Limit and Shakedown Analysis.

 

We are looking forward to your presentations at our symposium.

Best regards,

rate-state dependent friction in ANSYS

Submitted by Mike Ciavarella on

Dear collegues

a quick question:- I am playing with continuum models of Contact (Hertz, Westergaard and so on) and friction laws. However, I prefer for my students to use ANSYS FEM code. In Ansys there is standard Coulomb, rate-dependence but not rate-state (unless one codes some user subroutines). See

Enforcing tie constraint

Submitted by bfa on

Dear iMechanica users,

 

I have a problem which I would appreciate any input on how to solve. I have an indentation problem, in which I indent a cell with an enclosing membrane. Therefore, I create contact between the (rigid) indenter and membrane, and tie the membrane and intracellular solid elements together. The model is an axisymmetric model, with CAX3 and CAX4R making up the intracellular axisymmetric solid elements and SAX1 the axisymmetric membrane.

Simpleware Australia Workshops

Submitted by Simpleware on

Simpleware will be running a series of free workshops in Perth, Sydney and Melbourne from March 23rd to April 1st 2015

These will include an overview of using the software to visualise, analyse, process and generate models from 3D image data (MRI, CT, micro-CT...). Learn how to obtain very high quality models from image data, how to integrate CAD objects with images, how to calculate effective material properties using Finite Element-based homogenisation techniques, and about exporting robust FE and CFD meshes for simulation in other software.

Revisiting pyramid compression to quantify flexoelectricity: A three-dimensional simulation study

Submitted by Amir Abdollahi on

Flexoelectricity is a universal property of all dielectrics by which they generate a voltage in response to an inhomogeneous deformation. One of the controversial issues in this field concerns the magnitude of flexoelectric coefficients measured experimentally, which greatly exceed theoretical estimates. Furthermore, there is a broad scatter amongst experimental measurements. The truncated pyramid compression method is one of the common setups to quantify flexoelectricity, the interpretation of which relies on simplified analytical equations to estimate strain gradients.

Contact problem

Submitted by DRIDIAFEF on

Hello 

 

Iam trying to model an orthodontic apparatus movement. Can anyone help me how to choose the type of interaction between the three parts. In attached the assembly. THE steps are : the ring will be opened then it will descend finally the ring will return to its initial position can anyone tell me how to choose interaction properties. Thanksa  lot 

 

ABAQUS error

Submitted by Navid Moheb on

Hello everyone,

I am modelling a three dimensional cohesive element problem with Abaqus. I was wondering to see if anyone had the following error in their analysis:

THE NODE NUMBERING MIGHT NOT BE CORRECT FOR ELEMENT *** INSTANCE ***
