2. In engineering one of the most used systems for anchoring structures are bolted or riveted joining elements, being the aeronautical industry in which it is recurrently observed, such as in the fuselages and skins of aircraft, old aircraft, for this reason identifying the behavior of these systems is relevant. Therefore, this time it is intended to identify the mechanical behavior of the anchors shown in figures 2 and 3. Therefore, for each of the anchors determine: - The forces present in each of the bolts. - The efforts in the most loaded bolts. The stress and strain field in the plates. - The stresses and deformations in the stress concentration zones. - The computational models (FEM) for each of the anchoring systems. (Note: Define materials for both bolts and plates and for load selection, work at 75% yield strength). 50 mm d 10 mm R15 mm- 4x d 8mm 50 mm 25 mm - R10 mm 50 mm 50 mm 3xd 10 mm - 25 mm 200 mm Figure 2.
