A perspective paper on flexoelectricity by Professor Pradeep Sharma (University of Houston) is published in the March (2016) issue of the Journal of Applied Mechanics.  A perspective paper describes an important, emerging field in mechanics.  The first perspective paper, by Professor Huajian Gao (Brown University), has been downloaded more than 8000 times since its publication.  This new paper by Professor Sharma is the 3rd perspective paper published in JAM.  The paper is attached.

Huang's Crystal Plasticity UMAT taking into account Bauschinger effect for cyclic loading (kinematic hardening)

Submitted by Hidroxid on
Huang's UMAT; Crystal Plasticity; Cyclic Loading; Bauschinger effect

Hello,  

In the Crystal Plascticity UMAT model for Abaqus (by prof. Hunag) the Bauschinger effect which is important for cyclic loading, is not considered.  

Is there any edited version of this UMAT considering this effect for cyclic loading (by also considering kinematic hardening)?

 

Kind regards,

ANSYS terminology... confusing

Submitted by Echeban on
education
ansys

Why ANSYS calls the well known "element coordinate system" with their own term, "solution" coordinate system? 

Why ANSYS calls  the well know method of applying a "bias" for mesh refinement with their own term, "inflation"? -- I looked it up. INFLATION: to cause to expand or distend with air or gas.

Why ANSYS calls  the well know method of "partitioning" a solid model with their own term, "slice"? OK, may be "slice" is descriptive, but "inflation"? and "solution cs"?

Dear Colleagues

 

We kindly inform you that the Abstract Submission Deadline of the XVIII International Colloquium on Mechanical Fatigue of Metals (XVIII ICMFM) to be held in Gijón, Spain, has been extended until the 20th of February of 2016. Moreover, the registration is already open.

We would like also to remind you the organization of two Special Sessions in the frame of the Colloquium, being both still open to receive papers related with the corresponding topics:

A few experimental studies on the dynamic behavior of foam-like aligned carbon nanotubes

I'm posting a few experimental studies we have conducted on the dynamic behavior of hierarchical fibrous materials, using vertically aligned carbon nanotubes as a model material. I hope these will be useful to those who are interested in buckle-instabilities, multiscale behavior, and energy absorption mechanisms.

Special Volume of the International Journal of Fracture

Submitted by Ravi-Chandar on
International Journal of Fracture

As part of the celebration of the 50th Anniversary of the International Journal of Fracture, two special volumes were published in 2015. All articles of the 2nd 50th anniversary issue published in Nov/Dec 2015 are now freely accessible at the journal site until the 7th of April. These articles (and the ones published in the 1st 50th anniversary issue published in Jan/Feb 2015) provide reviews and perspectives on many aspects of fracture. You are welcome to browse thorough these articles and provide feedback on this blog!
