Characterization of acoustic cavitation in liquid-solid systems

PhD positions in Mechanical Engineering at Polytechnique Montréal

Submitted by etienne.robert on Mon, 07/31/2017 - 18:27

Fluid mechanics, combustion and acoustics

One PhD position is available in experimental fluid mechanics, more specifically on multiphase and reactive flows. The project aims at developing and characterizing techniques to manipulate and control particles suspended in gaseous flows, either upstream, downstream or in combustion zones. These techniques will include, but not be limited to, the use of acoustic forces to manipulate the particles.

How are principal planes & eigen vectors of the stress tensor related ? | An intuitive explanation

Submitted by rajan_prithivi on Sun, 07/23/2017 - 04:17

strength of materials

To obtain the principal planes we construct the stress tensor and find the eigen vectors. Here is an attempt to explain it more intuitively rather than the use of the formal mathematical method. Hope you enjoy this video!
---------------------------------

This is an educational outreach initiative targeted at all engineers interested in mechanics and seek simpler explanations. Kindly share if you learn something out of this !

Here is the link to the VIDEO

Ph.D. Opportunity at Singapore University of Technology and Design (SUTD) on Functional 3D Printing

Submitted by KevinGE on Thu, 07/06/2017 - 02:39

Prof. Ge’s Advanced Manufacturing and Design Laboratory (http://amd.sutd.edu.sg/) is recruiting PhD students. The Ph.D.scholarships are immediately available in the general areas of functional advanced manufacturing. The research topics can vary based on the student’s background from solid mechanics for soft active materials, UV curable functional polymer development for 3D printing, and development of high resolution multifunctional 3D Printing system.

What are Principal Stresses (explained without math equations) ?

In the following video, I have tried to explain the concept of principal stress in a more physical way and without involving any mathematical equations, hope you can easily imbibe the concept.

Here is my second video, where I tried to explain the concepts of stress state, principal stresses, Mohr circle and failure theories in layman's language and associated these concepts to explain the failure of a brittle material.
