Can i use stress from the predefined fields to apply confinement pressure for my SMA confined concrete model?

How to fix errors in my heat transfer steel structure with reinforced concrete slab model Abaqus?

I have modelled a steel structure using beam elements in Abaqus and attached to this structure reinforced concrete slab. The analysis that I am making is heat transfer of the structure. The...

How can I find the absolute maximum value of the Lamb-Oseen vortex with a no-slip condition?

R(t) = the propagation function of the vortex, where R=sqrt(4vt + R0^2) R0 = initial radius. w0 = initial angular velocity. Rf = the radius of the boundary confining the fluid. The Lamb-Oseen...

Zero pivot in Abaqus concrete 3D printing simulation using model change?

Recently I've been working on a simulation of concrete 3D printing, and has successfully simulated a layer-by-layer 3D printing process using model change. However, when I proceeded to try...

How to confirm if quantum confinement effect was occurred?

I'm making quantum well with 2 different bandgap materials, but I'm not sure quantum confinement effect was occurred because the well width is ~ 60 nm. How can I make sure that effect? Is there...

Why did the simulated load-displacement curve of beam keep increasing and didn't decrease (ABAQUS)?

Dear colleagues, I'm currently modelling a simple 4-point bending test of a concrete beam in Abaqus. However, the load-displacement curve was ascending (without final point), which didn't match...

Does the quantum confined effect affect the peak position of PL intensity?

The lower PL intensity for ultrathin MOF than that of bulk MOF also indicated a quantum confinement effect due to the ultrathin morphology of Cu-UMOF.
