A New Direct Tension Machine and its Application
In order to improve the efficiency of the direct testing machine for rock tension experiments, a new elastic foundation of lower clamper is used to replace the original rigid one. By using this direct tension machine, the complete stress-strain tensile curve of rocks sample was obtained, and the rock mechanical property was studied with this experimental result. Basing comparing the experimental result between the indirect and direct tension experiment, the authors recommend it may obtain the mechanical parameters by direct tension test as well.
