Numerous research works have studied the stress distribution in sections with
geometric discontinuities and the relationship with the theoretical factor of stress
concentration using the finite element method. These works have dealt with topics
such as the influence of the length of pieces on the 𝐾�𝑡� factor in rectangular
orthotropic plates; The behavior of the stress concentration factor on short shafts
with section changes under bending loads; The theoretical factor of stress
concentration in flat parts subjected to tension with "U" grooves; The estimation
of the theoretical stress concentration factor 𝐾�𝑡� for a flat plate with two holes
subjected to tension loads. Other studies have compared the stress distribution by
applying three methods: elasticity theory, finite element analysis and experimental
techniques. Results show that the finite element method is effective in solving the
problem.
The goal of this research is to determine the theoretical stress concentration factor
for a flat plate with two holes subjected to bending applying the finite element
method. The modeling of the plate, the application of the loads, the mesh
generation and the simulation of the stress distribution were made using the software ANSYS® Workbench. Four holes with different sizes were worked and for each
of them 10 different values of the distance between centers were taken. In this
way the relationship between the factor 𝐾�𝑡�, the size of the holes and the distance
between centers was found. This information is of great importance for the design
of mechanical elements that are under these conditions.
