Stress concentration in FEA refers to the concentration of stress at a specific location in a structural element, such as a beam or a shaft, due to the presence of a geometric irregularity or a change in the cross-sectional shape. This can lead to an increase in the local stress levels, which can result in a reduction in the overall strength of the structure. Stress concentration factors are used to estimate the increase in stress at these locations, and are typically determined using finite element analysis (FEA) simulations.

Not all scenarios encountered in product development are covered by the data found in the literature that is currently available. For many complicated structural components, it is impossible to compute Kt using the knowledge and techniques described in the literature.

For a variety of structural analysis issues, commercial FEM tools like ANSYS are frequently utilized in the automotive and aerospace industries.
