Hello everyone
I have a problem with SOLIDWORKS simulation, I would like to know the definition of zero strain temperature (in kelvin) and if there is any explanatory documentation on the results of the simulation study.
Sincerely, Karyll.
We don't have a lot of information on the subject in the help;

What settings you used in your external uploads.
What you need to understand for zero strain temperature!
If you are taking a part that is stationary and not subject to a constant force (without oscillation or vibration). The reference temperature will be the one you indicate in general 24.85° Celsius or 298 (K).
If, on the other hand, you know that the ambient temperature is 300° Celsius, it will be the one that will be the reference, all other things being equal.
What for?
If you have an aluminum part that is subject to bending (especially vibration deformations) and well given what we know about the temperature resistance of this material, the reference temperature for the zero deformation temperature will be 300°.
It must be remembered that a material subjected to frequencies (short vibration or long deformation) will see the areas subject to MAX stresses heat up (cf. matting). It is this heating (this warm-up) that will be added to the zero deformation temperature.
It is recommended to take into account the so-called "microstructural" evolutions which lead to variations in the density of the material and also to very significant dimensional variations.
Deformed materials such as spinning or fluo-turning and friction bending: are subjected to high heat under friction. It is also this peculiarity that is sought in the case of the incremental forming technique. (See here for incremental forming).
This temperature indication is also very useful for varying odds and games. In metrology, we are in a room with a stabilized temperature of 20° and the parts are stored there several hours before to have a stable temperature.
Remember the wire that is broken by twisting it and that is very hot at the places of breakage?
Kind regards
PS: for the record, there was a blacksmith in my village who, at the time of the village festival, demonstrated how to light a cigarette with a piece of cold metal (a shoeing bar). He would hit at a very high speed and violently, turning and turning the coin for several minutes, the coin being between a rock and a hard place, until he could light the cigarette. Atmosphere guaranteed to party.
thank you Alain
thank you Zozo nice the little story
Magnificent@Zozo_mp!
It's a pity that the time spent on this forum is not attributable to training time.
