The outputs are Max stress in rivets.
How should i define boundary condition on skin.Since in actual aircraft it is connected to other portion of skin and is constrained to move in the direction of flow of air. I have modeled only that portion of skin which is connected to my frame not the entire portion if i apply pressure in direction of air which in my case is negative x_direction the skin will simply move in that direction it will not be contrained in x_direction. How should i constrain it in that direction so it accounts for the part that it is connected with other portion of skin. Should i use displacement boundary condtion.
Simiularly How should i constrain my frame. Should i use inertial relief boundary condition. Fix support or displacement in this case as well.
