Hello all,

I'm trying to model the buckling of a shell structure under thermal load.

The structure is square-shaped.

The left edge must be kept straight. To achieve that, I applied MPC Tie Constraint for its nodes.

The bottom edge must be fixed so that the BC applied at its nodes was U1 = U2 = U3 = 0.

Temperature is applied as a predefined field.

However, when I run the simulation the corner that connects both edges deforms very strangely which makes me question how to model it.

I appreciate any input. Thanks.

This video explains the very fundamental points with regard to plasticity theory. It covers the following -

1) Why study plasticity ?

2) Additive decomposition of strain

3) stress and strength

4) Yield condition , flow rule & hardening rule

Applications are invited for an immediate  postdoctoral position within the Marine Additive Manufacturing Centre of Excellence at the University of New Brunswick. The candidate will perform research in the area of materials characterization of additively manufactured metals (aluminum or steels) developed through powder bed fusion techniques. The candidate will use several experimental techniques to characterize the 3D printed metals such as OM, SEM, EBSD measurements, fractography, and TEM.

Our recent review paper on how origami and kirigami techniques that could be used to create curved geometries has been just publised online. It is available as an open access article, which is why I am posting it here. We have also included some beautiful photos of our hand-folded origami and kirigami.

“Metamaterials” are the fabled materials exhibiting properties and functionalities that defy expectations. Or at least that's how I have always defined them to myself. These first emerged on the scientific scene in the nineties; or perhaps that is when an extensive flurry of activities on this subject can be traced to. The initial focus was on designing (what appeared to me as) composites with a specific geometrical inner structure that allowed the emergence of electromagnetic properties not typically seen in nature; such as negative refractive index.

The Institute of Mechanical Engineering is soliciting applications for a faculty position at the level of tenure-track assistant professor in Thermal Sciences.
