We invite you to participate at our session on Physics and Mechanics of Ductile Failure: Modeling and Experiments at ASME 2016 IMECE to be held in Phoenix, Arizona, USA during November 11-16, 2016.

The deadline for submission of abstracts is March 7, 2016. The session is organized under Track 12,  #12-35 Physics and Mechanics of Ductile Failure: Modeling and Experiments.

Hello everyone,

I was looking for a Matlab source code for implementing XFEM to solve a dynamic problem (specifically dynamic crack propagation problem). I found several source codes which only solve static problems (they don't calculate mass matrix and they don't do the time integration). 

My research goal is to remove the oscillations from stress intensity factors  for a dynmic crack propagation problem. I will really appreciate any kind of help/suggestions.

With respectfully

Starting April 2016, we will have openings for two post-doctoral fellow positions in experimental and computational mechanics of advanced polymers. These positions will support a new research program between Singapore University of Technology and Design (SUTD) and National University of Singapore (NUS) funded by Agency for Science, Technology and Research (A*STAR). The project focuses on synthesizing, characterizing, modeling, and simulating the thermo-mechanical behavior of polymers with covalent adaptable networks (CANs), e.g. vitrimers.

We have two research positions, available in November 2015, in the area of micromechanics of advanced structural steels. The first one is a post-doctoral research fellow (RF) position. An ideal candidate for this position must possess a PhD in mechanical engineering or related field with a strong background in computational materials mechanics. Experience of developing mesoscale methods such as dislocation dynamics or crystal plasticity and mesoscale fracture mechanics will be a definite plus.

A Virtual Special Issue of the Journal of Non-Newtonian Fluid Mechanics devoted to yield stress fluid flows has just been released. With this first Virtual Special Issue of the journal we inaugurate a practice, which we plan to make regular, of highlighting developments on a particular subject of relevance in order to guide and encourage research in the field.

There is a Post doc/RA position related to Metallic Micolattices and their energy absorption applications.

I apply force using one slider to another slider. Best part is one slider move little bit and help second slider to slide 6 times length at 70 % force.

Energy Used to move first slider=force*distance

=100N*0.05m

=5Nm

Energy Get on Other Slider= Force*Distance

=Force applied by first slider*cos(45`)*distance
