Dr. Schmid performs varied research in many aspects of manufacturing, especially in tribological applications in manufacturing. Recent projects include research on the mechanisms through which emulsions lubricate metal rolling and ironing, development of new friction and heat transfer models for use in finite element simulation of forging and metal working operations, use of environmentally friendly polymer coatings in ironing, and novel forming and fabrication schemes for metal foams.
Lubrication, friction and wear problems have traditionally been subjects which were investigated, both experimentally and theoretically, at macroscopic scales, even though important phenomenon occur at the sub-micron level. For example, a surface asperity on a tooling surface will penetrate and plow a workpiece in an extrusion operation, but the maximum depth of penetration is only one-half a micrometer or so. Current research emphasizes single asperity plowing simulation in an atomic force microscope and correlation with a mathematical model based on the upper bound theorem of plasticity.
Dr. Schmid is involved in the design and manufacture of new types of orthopedic implants. One area deals with the design of new types of implants that are less invasive than traditional ones. For example, a new hip fracture device is under research that involves a 25 mm incision instead of the traditional 300 mm incision, and which does not require any dissection of soft tissue for implantation. Dr. Schmid is also developing new forms of bone ingrowth scaffolding and artificial cartilage.
