Hello!
I have some problems in a project:
In the geometry I attached to this message I designed a part of tensile test sample to simulate the stress and strain in the sample. Between the upper, broader rectangle and the lower, slimmer rectangle I placed a cubic bezier curve with the points PT1, PT2, PT3 and PT4 as a connection.
In the CAD-model of this sample (that I'll send to the person producing the sample to make experiments in the end) I'll have to construct this connection with two circles with tangentially constant transitions to the upper rectangle, to the lower rectangle and between the circles.
No my big question is:
Will the comsol-model and the CAD-modell be the same (or almost the same)?
And will it still be like this, if I, for example, place PT4 a bit lower to make a smoother transition (I would also change the CAD model with giving the lower circle a bigger radius and changing its place a little bit for a smoother transition)?
If I just put circles over the comsol model do find it out by myself it looks quite similar, but I'm not sure about the mathmetics...
An answer would rescue me! Thanks a lot in advance!
Greetings,
Frederik
PS: Sorry if my English isn't the best, especially at the technical terms, I'm from Germany.
