Abstract: This paper presents a new model of the drilling response of roller-cone bits. First, a set of relations between the weight-on-bit W, the torque-on-bit T, the rate of penetration V, and the ...

Abstract: The use of mechanical anchorage systems can delay or prevent premature failure of RC structures with externally bonded fiber-reinforced polymer (EB-FRP) laminates. This work reports the results of an experimental program ...
