A computational study of flexoelectricity

Flexoelectricity is a size-dependent electromechanical mechanism coupling polarization and strain gradient. It exists in a wide variety of materials, and is most noticeable for nanoscale objects, where strain gradients are higher. Simulations are important to understand flexoelectricity because experiments at very small scales are difficult, and analytical solutions are scarce.

VUMAT Subroutines for multi-phase material behavior.

Hi everyone. I would like to know how to get started with a VUMAT subroutine for multiphases for example a subroutine for pore water and sand. It could be helpful when anyone could share VUMAT subroutines for learning such complex programmings. Could be appreciated when some one teaches with equations. thank you.

Extremely Curved Cracks


The word "extreme" seems to be "trending" a lot these days, see the recent discussions on the new journal Extreme Mechanics Letters.

My collaborator Ruben Sevilla at Swansea and I were interested in very curved crack paths that develop in nature and have been replicated experimentally in thin films attached to elastic substrates.

Journal Club Theme of September 2014: Numerical modeling of thermo-hydro-mechanical coupling processes in porous media

Thermo-hydro-mechanics (THM) is a branch of mechanics aimed to predict how deformable porous media behave, while heat transfer and fluid transport simultaneously occur in the pores filled by liquid and/or gas. Understanding these multi-physical responses is important for a wide spectrum of modern engineering applications, such as tissue scaffolding, geothermal heating, mineral exploration and mining, hydraulic fracture, energy piles, tunneling with frozen soil and nuclear waste storage and management.

Rapid review and publication at JAM in 2014

Journal of Applied Mechanics (JAM) received 280 submitted manuscripts during the first 6 months in 2014.  Among them only 4 are still in review.  

The average time for the 1st round of review, with the decision to accept, or reject, or revise, is reduced to 10 days.  For those that need revisionsthe average time to make the final decision is 24 days after the 1st round of review, which include both the authors' revision time and 2nd (and more) round(s) of review.

Vibro-acoustics (2 positions)

Noise is one of the vitally important factors determining the quality of life and liveability in urban areas. We have awarded a grant to develop novel windows enabled with green and intelligent sound absorbing materials that have substantially reduced noise transmission, and at the same time maintain ventilation function to realize good thermal comfort and resource efficiency.

How to model metal flow using ANSYS APDL??


I am trying to model Friction Stir welding using ANSYS APDL. I have two plate . By meshing I have created element on the plate. I am trying to move these element from one plate (advancing side) to other plate(retreating side) while the pin tool is rotating. Does anyone have any  idea how to do it on ANSYS APDl?

new paper on fracking in JAM by Prof. Bazant

Fracking has been an important research topic in recent years.  JAM just published a paper "Why Fracking Works" by Professor Zdenek Bazant and his co-authors (JAM, volume 81, paper 101010, 2014).  This paper is of great interest, not only to mechanics, but also to engineers interested in fracking.

The paper is attached.

Question regarding the crack propagation direction in Abaqus

I am developing a 2D model in Abaqus v13 in order to study the fatigue properties of a plastic material in oxidative atmosphere. I am using the direct cyclic approach and the XFEM technique. When defining the crack propagation direction I can just select:

-direction perpendicular to the element 1-direction

-direction perpendicular to the element 2-direction

-maximum tangential stress criterion

I am wondering how to implement other criteria. I cannot find any specific subroutine able to deal with this. Any help would be greatly appreciated.

EMI 2015 Conference

EMI 2015, the annual conference of the Engineering Mechanics Institute of ASCE, will be held at Stanford University on June16-19, 2015. It will be chaired by Prof. Ronaldo Borja ( Department of Civil Engineering, Stanford University).
