Using engineering to understand biological processes

Submitted by Lee Margetts on

All
I'd like to share the following paper with you. I think its an interesting example of where
engineering knowledge can be used to help understand biological processes. We used microscope work and finite element analysis to test a hypothesis as to how a biological structure, crimp, forms in tendons. We'd like to continue this work, so all comments welcome.

Hardness value from Nanoindentation Curve

Submitted by atiwari on

nanoindentation

Hi,

Is there anyone aware of the reason why there is a surge in hardness value during the initial stages of penetration in nanoindentation curve. In a plot of hardness vs displacement into surface, I record a high value during the initial stages of the run. I am little confused about the reason.

Thanks,

Hi every body

I wanted to know what should we do when we found a scientific problem in a

published journal article, is it impolite to inform the journal Team?  Or we

should discuss it with the authors of the article?

Fluid structure interaction with Abaqus

ABAQUS
Fluid Structure Interaction
abaqus/cfd

Hi,

 

I'm looking for tutorials or example problems on carrying out Fluid Structure Interaction simulations using Abaqus.  

I have a large amount of experience with Abaqus Standard however Abaqus CFD is very new to me.  Would anyone have the training course notes on either "introduction to "ABAQUS/CFD" or "FSI Simulation with Abaqus"? If so, I'd really appreciate a copy.

 

Thanks

Dear Colleagues,

I am studying on Interlaminar Properties of 3D Textile Composites. Especially I am focusing on Fracture Toughness of Stitched Composites. Anyone can suggest useful Journal Papers about Stitched Composites and/or Mode I- Mode II Testing for Literature review?

Kind Regards,

Devrim Goktas 

 

 

How to simulate boundary conditions and apply uniformly distributed load to shell element when I do nonlinear analysis of I-BEAM

Submitted by speedeagle on
research

Hi, everyone:

I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.

When I simulated the beam with shell element, first I define reference points at both end of the beam and assign 'RIGID BODY/PIN OR TIE' to  nodes at the edge,after that I applied bending moments and boundary conditions to both reference points.  But after I finished the buckling analysis, the result is not reasonable,the eigen value is about two times the the value I expected.
