Postdoc position in nanoscale fluid-structure interaction at QMUL London (ERC project FLEXNANOFLOW)

Submitted by exw569 on

A postdoctoral research position in computational soft matter will soon open in the Division of Engineering Science, School of Engineering and Materials Science, Queen Mary University of London (QMUL). Queen Mary is part of the Russell group of elite, research-intensive UK universities, and provides an attractive campus environment within the heart of London. 

ABAQUS: Access stress of integration point of elements during calculation

Submitted by Linhbkxd on

Hi all,

I'm using ABAQUS and UMAT for structural simulation. I used quadratic element (CPS4) with 4 integration points (IP).

During the calculation (which calling my UMAT), at each time step, for each element, I need to calculate the average stress of these IPs and produce a state variable for these IPs from this average stress. Then, I would need to update this state variable back to these IPs in that element. But as far as I know, the ABAQUS call UMAT for every IP and calculate everything within this current IP.

Nature paper about mechanical metamaterials violating Betti's theorem

Submitted by Mike Ciavarella on

Maybe because I am proud of Betti's theorem being italian, I am curious about this big emphasys on systems violating it.  They may "open avenues for energy absorption, conversion and harvesting, soft robotics, prosthetics and optomechanics".... ?  I'd be curious to hear some comments.   Anyway, the last author Andrea Alu is anyway italian like Betti.

A postdoctoral associate position at Department of Petroleum Engineering, Texas A&M University

Submitted by srabeedii on

A postdoctoral associate position is available at Department of Petroleum Engineering, Texas A&M University in the area of resistivity characterization of geomaterials. Experimental characterization at nano-scale will be combined with modeling techniques to get insight into electrical properties of geomaterials at fundamental length scales. 

Expected qualifications:
A Ph.D. in materials science, engineering or a related field is required. The candidate should have a strong background

On structured surfaces with defects: geometry, strain incompatibility, internal stress, and natural shapes

Submitted by Ayan Roychowdhury on

Given a distribution of defects on a structured surface, such as those represented by 2-dimensional crystalline materials, liquid crystalline surfaces, and thin sandwiched shells, what is the resulting stress field and the deformed shape? Motivated by this concern, we first classify, and quantify, the translational, rotational, and metrical defects allowable over a broad class of structured surfaces. With an appropriate notion of strain, the defect densities are then shown to appear as sources of strain incompatibility.
