If I name the area as ##\Gamma_c## then it could be written this way ?

Do I also perform inner product of stress with the normal vector of the surface when I integrate the stress over the area?

##u## is the displacement along x-axis and ##v## is the displacement along y-axis?

Thank you! The displacement should be zero at the fixed end (at the left) because of the fixed support and also no rotation is allowed at the fixed support

Thank you so much!

It's Sfepy

I'll ask him and let you know soon, as he's away for a conference.

Thank you. May I know please why it becomes much complicated in 2D? Do these equations make sense for example? $$\sum F_x = 0 \quad \Rightarrow \quad F_x - \int_{\Gamma_c} \sigma_x \, dA = 0$$ $$\sum F_y = 0 \quad \Rightarrow \quad F_y - \int_{\Gamma_c} \sigma_y \, dA = 0$$ $$\sum M = 0 \quad...

Thanks. So as stated in answer #9, these equations are also for 2D? What about if I wanted to write the equations not only interms of forces only but also in terms of the stress of the elastic body.

Ok so, the original problem is that the elastic body is piezoelectric. And no only that, it is a bimorph. It is about optimization but taking into account the applied force. It is a big problem but my professor was only commenting on the equations regarding the rigid body (equilibrium) so he...

The basic thing is that I needed to write the full equilibrium equations of the rigid body as my professor said. But then I realized that I might need to substitute for the stress which is done by using Euler bernoulli assuming small displacement, but then I was hesitant again of whether I just...

Hello, thank you! These equations are correct also in 2D right? I feel a bit confused regarding moving from 1D to 2D, because in 2D we'll have not only a point B connecting the two objects but a surface in common. In case I need to write the force in terms of stress of the elastic body, we...

Thanks! I'll watch it

My actual problem is actually bigger than this and has more equations and conditions and my goal is to model my state problem and to solve it using a numerical software (FEM). But I needed to correct the equations of equilibrium of the rigid body and I simplified the problem further in order to...
