Abstract

Ring-Core method is derived from a hole-drilling method and both are used for determining uniform and non-uniform stress through the thickness of specimen. The reason for creation the Ring-Core method was to remove some of the shortcomings of hole-drilling method. Both methods are semi-destructive methods, because they both partially destroy the studied specimens which are subsequently easy to fix and thus they are still useful. The aim of this article is to compare these two methods and thus help experimentalist to choose the appropriate method for determining residual stresses. Because Ring-Core method is less common, we will discuss more about this method in the article.
