摘要： A reinforcing metal blank may be used to form metal matrix composite (MMC) drill bits. For example, an MMC drill bit may include a shank attached to a reinforcing metal blank that extends into a bit body comprising a metal matrix composite, wherein the reinforcing metal blank comprises reinforcing structures that are positioned along at least a portion of an inner surface and/or at least a portion of an outer surface of the reinforcing metal blank and extend into the metal matrix composite; and a plurality of cutting elements coupled to an exterior portion of the bit body.

摘要： A strain magnification apparatus can have a first section and a second section coupled with the first section. The second section can have a lower stiffness relative to the first portion and a strain gauge coupled thereto. The first section is operable to be coupled to a tool experiencing strain and the tool is formed from a material having lower elasticity than the second section.
