Using Nano Scratch Testing For Composite Failure

One of the major concerns for composite material is it’s durability in final form. The size of particles that form the strengthening additive can drastically affect the overall final performance of the composite material. By using the nano scratch testing method the failure of composite material can be compared to identify the most durable formula.

ADINA Electromagnetics

We have recently added the ADINA Electromagnetics module (ADINA-EM) to our wide range of multiphysics offerings. Using this module, the general Maxwell's equations can be effectively solved and the resulting electric and magnetic fields can be coupled to the fluid flow. For details please see:

Open source Matlab toolkit now includes 3-D beam elements

The FAESOR toolkit now incorporates a linear and geometrically nonlinear formulation of three-dimensional beams. Some updates and fixes have also been posted.

Rodney Hill died on 2 February 2011

Rodney Hill was born on 11 June 1921.  He was a Reader, then Professor, in The Department of Applied Mathematics and Theoretical Physics (DAMTP), of The University of Cambridge, during the period 1969-1979. He is widely regarded as among the foremost contributors to the foundations of solid mechanics over the second half of the 20th century. He was author of 'The Mathematical Theory of Plasticity' published in 1950.

On proposals

Every year I try to get funding for things that I'm personally interested in but which may not have any immediate economic benefits.  A couple of years ago, after reading Penrose's "Road to Reality", I thought about applying Clifford algebra ideas to fracture mechanics and wrote up a proposal to that effect.  The proposal wasn't funded, but I think the idea is worth exploring.

The summary of the proposal was

From the literature

Naturally negative bulk modulus material.

 

Negative Linear Compressibility and Massive Anisotropic Thermal Expansion in Methanol Monohydrate

material parameters calibration for crystal plasticity

Hi

 I am doing the crystal plasticity analysis of tensile test, at the first step in order to calibrate my model

I can use either force-displacemnt or stress-strain curve I was wondering which one is better to use, I am using abaqus-explicit

Fatigue

Hi,

 I d like to ask you how could fatigue loading be modelled in cae. I know that you can set up the load as a sin function with min and max values. But where do you set-up the total nr of cycles? Is at the step part and where exactly?

And another question could anyone provide me with details of the input file for the hysteresis loop, where the stess nd strain resistance of the material drops after certain cycles..

 

Regards,

Extrude a solid section

Hi all,

       I am having some troubles with the extrude command in Abaqus cae. I have modeled my sample as a 2-D geometry and now I want to move to 3-D for the same section. But I am having trouble extruding my 2-D section. It seems to me very weird and far to complicated the extrusion process in abaqus for such a simple task...

Thank you,

          Panos

Discussion of fracture paper #1 - A contol volume model

This is a premiere: my first contribution to the new ESIS' blog announced in January. Why comment on papers in a scientific journal after they have passed the review process already? Not to question their quality, of course, but animating a vital virtue of science again, namely discussion. The pressure to publish has increased so much that one may doubt whether there is enough time left to read scientific papers. This impression is substantiated by my experience as a referee.

What would you like for an undergraduate book on QM to explain to you?

 

1. Background:

A couple of things concerning books happened recently, in the last week or two.

(i) Dr. Biswajit Banerjee announced last week that a new book on metamaterials and waves in composites authored by him is coming out in print within a few months.

Difference between plastic and Elasto-plastic deformation

Hi all

      What is the difference between plastic deformation and Elasto-plastic deformation? Thank you all.

Forging process simulation

Hello friends,

I am doing My Graduation in Mechanical, right now i am on a project and want to simulate Forging cylinderical billets in order to optimise the process parameters, hence it is required to optimize the process parameters like temp., speed , stroke, material flow etc. as a function of Die design and friction. I want to simulate it in ANSYS plz help me how to go for it, because finally i want stress, strain rate, strain, material flow as the final  result.
