Abstract Residual stresses exist in the material as a result of the manufacturing process; do not occur due to forces on the object in use. The residual stress analysis is very important because with early detection it is possible to prevent an object from failure. Nowadays there are several methods for the measurement and determination of residual stresses. The article deals with the semi-destructive Ring-core method, which is not used in Central Europe. Information given by this article will be interesting for the reader since the article contains a short introduction the history of Ring-core method and application of the strain gage on the surface of specimen as applied for Ring-core method.
