A method for estimating shear stress distribution on a fault surface during frictional sliding is studied using a three-dimensional thermal conduction model which takes both the finite area of sliding surface and non-uniform distribution of heat source into account. The theoretical temperature transient curves derived from the three-dimensional thermal conduction model are in much better agreement with the observed ones gained from our experiments than those derived from the one-dimensional model usually adopted to analyze observed temperature data (LOCKNER and OKUBO, 1983; YOSHIOKA and SHIDAHARA, 1978). The results show that there is non-uniform shear stress distribution on the sliding surface during frictional sliding.
This method is applicable to other types of frictional experiments for estimating the temperature rise and energy budget on the sliding surface.
