Is there any existing open source code (preferably FORTRAN) to compute stress and strain from the 3D model displacement ?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10?

What's the best way to measure growth rates in House sparrow chicks from day 2 to day 10? Since, the growth curve from day 2 to 10 won't be like the "Logistic curve" it might not follow logistic...

What techniques can I use to determine the miscibility of polymer blends?

The term miscibility refers to the single-phase state in thermodynamics. I do not mean the compatibility of different components. To determine the miscibility I know several techniques such as...

How to repeat an operation on an atom selection for multiple times in PyMol?

Hi, I am trying to construct a multi-layer fibril structure from a single layer in PyMol by translating the layer along the fibril axis. For now, I am able to use the Translate command in PyMol...

Shall I skip the measurement model in SmartPLS?

Hello everyone, I had run a mediation model in SmartPLS using questionnaires that were already validated among my statistical population. A professor who edited my paper -though she is not...

LOAD DISPLACEMENT CURVES Stiffness increasing in ANSYS non linear analysis. HOW CAN I CORRECT IT?

Hi. I am doing non linear FE analysis using a new material beam under flexural 2 point loading using ANSYS. I have defined a bilinear material model. The solution has converged. In results I am...

What is involved in morphological changes of SEM images of a substance?

In the sem analysis of CaCO3 nanaoparticles, the morphology images showed spherical shaped particles but the proposed morphology for these type of nanoparticles is trigonal. I prepared the...

How to define tie constraint between rigid body and another part in dynamic explicit model of Abaqus?

Hi dear researchers I connected a rigid body into the part of my structure by tie constraint and then I added displacement to rigid body, in static general step every thing is fine and these two...

Does the circuit modeling for planar monopole antennas using Foster canonical forms give good approximation?

Hi researchers, I am searching for some accurate way to do the circuit modeling of planar CPW-fed monopole antennas. I have gone through the literature where mostly circuit modeling is done using...

I do not know about Fortran and not so much about FEM link - but you could feed your data into 3D DIC (digital image correlation) software - that's precisely what is doing. For instance our (disclaimer) open source PIV software, www.openpiv.net is producing displacements, and these are transferred as data tables to the 3d DIC software, e.g. this open source one: https://github.com/MultiDIC/MultiDIC

Probably a little bit outdated, but good old NASTRAN is available on Github: https://github.com/nasa/NASTRAN-95
