Hello everyone,
I am doing a project in FEM, and we first have to assess the mechanical behavior of a connecting rode in which there is a hole in the center part of height b. The connecting rode has a trapezoidal shape (when seem from the top view), so the cross section is gradually decreasing from the big articulation, with an angle of 5°. The connecting rod is subjected to a distributed force P (oriented to a degree alpha) on its small articulation. I have two questions, hoppening someone will answer to them:
1° How can I write the static boundary conditions on the inner surface of the small articulation: T_j = n_i sigma_ij ?
2° How do I compute the first moment of area of the cross-section of the center part (with the hole, so two discontinuous rectangles), knowing that the height changes along the longitudinal axis?
I don't know how to join files in here, but if you tell me, I can provide some to understand the background.
Thank you !
