Complex Analysis of the Necessary Geometric Parameters of the Tested Component in the Ring-Core Evaluation Process
Keywords:residual stress, Ring-Core method, finite element method(FEM), incremental method, differential method, integral method
Residual stress measurement in different sorts of mechanical and mechatronic objects has become an important part of the designing process and following maintenance. Therefore, a sufficient experimental method could significantly increase the accuracy and reliability of the evaluation process. Ring-Core method is a well-known semi-destructive method, yet it is still not standardized. This work tries to improve the evaluation process of the Ring-Core method by analyzing the influence of the necessary geometric parameters of the investigated object. Subsequently, residual stress computation accuracy is increased by proposed recommendations.
