Determination of the strength of rocks is very troublesome since it takes much time and effort to produce good test pieces. Therefore some methods for rapid determination of the strength of rocks are strongly demanded. The authors have investigated how to determine the strength of rock with irregular test pieces, i. e. rock pieces which are not machined. By theoretical as well as experimental study, they have obtained such a method to determine rapidly the tensile strength of rocks that an irregular test piece is crushed into two pieces by a concentrated load F, the distance between the points of loading being 2a, and then the tensile strength of the rock is given by 1.4 F,2002
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
