How to deal with peak stresses on Ansys Structural (Mechanical)

 - **Stress averaging**: This method is used to smooth out the stress distribution by averaging the stresses over a certain area or volume. This can reduce the effect of local stress concentrations and provide a more realistic estimate of the average stress in the structure. However, this method may also hide some important stress variations and details, and may not be applicable for complex geometries or non-linear problems. You can read more about this method [here](^1^).

- **Submodeling**: This method is used to perform a detailed analysis of a small region of interest within a larger model. This can increase the accuracy and resolution of the solution in the region where peak stresses occur, without increasing the computational cost and time for the whole model. However, this method requires careful selection of the submodel boundaries and loading conditions, and may not capture the global effects of the structure. You can read more about this method [here](^2^).

- **Singularity elimination**: This method is used to modify the geometry or boundary conditions of the model to eliminate or reduce the singularities that cause peak stresses. Singularities are points or lines where the stress becomes infinite or undefined, such as sharp corners, re-entrant angles, or point loads. By rounding off the corners, adding fillets, or distributing the loads, the singularities can be avoided or minimized. However, this method may also alter the actual behavior of the structure and introduce errors or uncertainties. You can read more about this method [here](^3^).

These are some of the methods that can be used to deal with peak stresses on ANSYS. I hope this helps you understand them better. I
