1. A method for designing a drill bit, the method comprising:
- selecting bit design parameters;
selecting parameters of an earth formation;
selecting drilling parameters;
simulating drilling the earth formation;
calculating a bending moment acting on the drill bit;
converting said bending moment into a visual representation;
varying at least one of the bit design parameters and repeating the simulating and the calculating until the bending moment meets a selected criterion, andgraphical displaying the visual representation.

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.
