Strong background in Mathematics, Nonlinear Dynamics, Vibrations and Control

Submitted by Neda.km on

Hi 

I have B.Sc from Sharif University of Technology, Iran and M.S. from Northeastern University in  Boston, US, both in Mechanical Engineering.

I have a strong background in Mathematics, Nonlinear Dynamics, Vibrations and Control, and some years of related experience in these fields. Furthermore, I do have a great deal of the programming skills and computational methods with an extensive computer software knowledge. I am also interested in working on Vehicle Control, Robotics, Tribology (friction and surface sliding) and Vibrations.

Can you "chop" a mechanical wave?

Submitted by Ahmed Elbanna on

In this paper we highlight several interesting phenomena that may emerge from coupling simple elastic systems like 1d bars. While in compostes we usually focus on wave propagation normal to the stratification direction (composite layers are coupled in series), here we show that extreme attenuation at multiple frequencies may emerge in linear systems that are coupled transversaly. We also introduce a simple device that act as a chopper for mechanical signals.

Grad Student Openings: University of California Merced - Mechanical Engineering

Submitted by amartini on

There are PhD and MS openings at the University of California Merced in the Mechanical Engineering Department. UC Merced is the newest campus of the well-known University of California system. Because the campus is still relatively small, most incoming graduate students are funded via Teaching Assistantship or Graduate Research Assistantship. Also, the application fee will be refunded for students who are admitted and join the program in the Fall. The application deadline is January 2018.

PhD position in computational mechanics

Submitted by Arttu Polojärvi on

We are looking for a doctoral student to work on numerical modelling of fragmentation of quasi-brittle materials. In more detail, you will study breakage and fragmentation of ice blocks. These phenomena occur under compressive loads in ice block to ice block contacts. The fragmentation process is complicated, and requires novel numerical modelling techniques. Modelling may need to be done on different scales, which may have to reach from very high resolution modeling to simplified contact models on larger scale.

ABAQUS - the influence of changing kinematic and cycling hardening parameters

Submitted by szyfuj on

Hello,

 

I have recently done a simple hourglass model to check the influence of hardening parameters in Abaqus. The reason was the effects of the parameters' change in bigger models were a bit surprising, therefore I needed to investigate the reason using some simpler model. Please see file 1.

 

After performing tension/compression cycles I got results as shown in files 2, 3, 4 and 5. Please note that only the hardening parameter in the description changes, the other three stays the same for each series.
