Hi all,

 

I have a question about an FEA simulation. Particularly, about the boumndary conditions that need to be applied to run this simulation. 

 

attempt1:

 

I fixed the right end of the plates and applied loading to the left end. This resulted in stresses go through only the top joint region (W1 in figure attached). 

 

From our understanding, the deformation is got to be symmetric on both the plates. But, when we applied these BCs, it is not smmetric.

PhD; computational materials science

Research assistantships are available for students interested in pursuing Ph.D. degree in Materials Science and Engineering. The graduate students will join the Computational Materials Group and work on the development and application of various computational techniques (atomistic, continuum, mesoscopic) to research problems in general areas of laser – materials interactions, acoustic activation of surface processes, and investigation of properties of nanostructured materials.

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.

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 !
