Abstract
A computer-implemented method of designing a downhole drilling tool may include generating a three dimensional (3D) downhole drilling tool model including a plurality of cutting elements on a plurality of blades and simulating engagement of the 3D downhole drilling tool model with a 3D model of a borehole bottom. The method may further include calculating a cutting force of a cutting element of the plurality of cutting elements, calculating a wearflat frictional force of the cutting element, and modeling a drilling efficiency of the 3D downhole drilling tool model based on the cutting force of the cutting element and the wearflat friction force of the cutting element. In addition, the method may include determining a design parameter of the 3D downhole drilling tool model based on the drilling efficiency of the 3D downhole drilling tool model.
