How to synchronize two stepper motors most optimally?

We need to push a large load (2 tones) using two stepper motors, connected rigidly to the axis (two screws). I'm worried the motors could micro-step out of sync. And cause malfunction. I can see...

Strain controlled fatigue tests?

I'm working in geotechnics. We are testing "fatigue" response of cyclic loaded sand, where deformation cycles (or strain cycles) of constant amplitude are applied. I need references to research...

Paradigm shift. What to do if observations fundamentally contradict convention

Asked 3 minutes ago I have a problem. Measurements show the opposite of what convention assumes. It occurred in geotechnics, but could affect all material modelling branches. I tested soil...

Large strain compatible FEM (20% strain range)?

I am trying to make a sand model, which captures liquefaction / post-liquefaction recovery around a structure. We have the laboratory results and measurements, but to use them a model stable at...

Paradigm shift. What to do if you the observations contradict the convention?

I have a problem. Measurements show the opposite of what convention assumes. I test soil specimens. We try to decode how much deformation a certain loading (force) sequence will generate. After...
