ABSTRACT:
A method for designing a roller cone drill bit comprising selecting bit design parameters, selecting parameters of an earth formation, selecting drilling parameters, simulating drilling a selected earth formation, determining force on at one of a cutting element, a cone, and a drill bit, determining a location of the force, calculating bending moment, and varying at least one of the bit design parameters and repeating the simulating and the calculating until the bending moment meets a selected criterion. The method further comprising converting said bending moment into a visual representation.
