I'm working on a part which has a recess diameter of 88.04 (+0.1, +0.3)mm. The adjacent flat surface must (because I want to understand the shenanigan) match the equivalent profile tolerance with the (U) option. (Sorry for image quality, some number "3" look like number "2") Is it possible to...

I just saw a method for calculating the fatigue with Goodman diagram which involves the equivalent von Mises stress. Normally, von Mises is only positive. Those 2 methods allows to add a "sing" to the von Mises value. Method 1: - Take the diagonal of the constraint tensor : diag([s_ij]) = [S1...

Hi, I work on a shaft which is taking a part sandwiched between a nut and the shoulder of thus said shaft. Before installation of the shaft into an assembly, the nut is torqued at 75 Nm. Once the nut screwed, the torque of 75 Nm is relaxed. So the equilibrium of the nut is as follow : An axial...
