Experimental research of loading rate effect on brittle-ductile transition of mudstone under high temperature

ABSTRACT
To investigate the brittle ductile transformation characteristics of mudstone under high temperature, the MTS810 electro mechanical hydraulic servo test system and matched high temperature furnace MTS652.02 are used to perform mechanical tests to study the influence of loading rate on the yield strain and ductility coefficient of the mudstone at high temperatures.
