The deformation localization theory of cutting of coal and rock

Qi Wang

Open publisher page 0 citations

Abstract

when the strain is intensively localted in narrow shear band, this phenomon is called localization. This paper introduces the phenomen and theory of deformation localization of rock and coal.The numerical method has been used to study the process of localization. The white light digtal speckle corelation method has been used to study the process cutting of coal. The localization phenomena has been found and the localization theory of coal cutting put forward.
