A quasi-plane strain experimental device is designed. This device is implemented to analyze deformation localization phenomenon of Chongqing red mud-sand stone in quasi-plane state. Some specimens are tested in various loading speeds; and some are researched with different water contents. During the experiment
the onset of deformation localization has been monitored by elastic wave. The results show that
in quasi-plane strain state
there is a logarithm-like relation between the angle of localization band and loading speed. It is also shown that the water content could impact on the onset of deformation localization.
