The finite element method (F.E.M.), often known as finite element analysis (F.E.A.) is a design tool based on a numerical process which offers an approximate solution with enough precision for engineering independently how complex the geometry or the actuating loads are. However, the precision is function of many variables and there are some possibilities to jeopardize the result. The most important of all is the stress singularity.The target of this work is to demonstrate the stress singularity problem on a real automotive part and the way to solve it. The main contribution of this theoretical engineering analysis is to avoid a wrong interpretation of the F.E. results during the product development process.
