The introduction of PDC bits in the oil well industry by General Electric in 1973 was a significant advancement in drilling technology. To understand the potential of these bits, cutting mechanics and heat transfer models were previously developed. I

Summary A heat-transfer model based on the finite-element method is developed for synthetic polycrystalline-diamond-compact (PDC) cutters used in oil well drill bits. The model is verified by comparison with single-cutter experiments. Effects of proc

Abstract Assuming that rock behavior, during cutting with a single diamond, may be approximated by that of a rigid, Coulomb, plastic material, a theory of single diamond cutting action has been developed. Using this theory, the stresses on the diamon

Abstract With, the assumption of perfect cleaning, a theory of the drilling performance of surface set diamond bits has been developed. The analysis is based on the previously developed theory of the cutting action of a single diamond, in which it wa

The problem of self-sustained vibration of an autonomous system is considered. Sufficient conditions for functions which bound a limit cycle in the phase plane are established. A procedure is presented whereby practically useful bounds for a limit cy

Summary A principle relating to convergent upper and lower bounds in certain continuous boundary value problems is presented. The procedure is discussed in detail for a fin temperature problem in which there is internal heat generation. A numerical e
