Dr. Beuth’s research interests are in the area of solid mechanics and manufacturing. Much of his research relates to his expertise in the areas of thermomechanical modeling of manufacturing processes, fracture mechanics, and the mechanics of coatings and layered materials. One area currently being investigated relates to Mechanics of Electron and Laser Beam-Based Additive Manufacturing Processes, which are automated processes for directly building three-dimensional parts or features, layer-by-layer, via electron beam- or laser-based deposition. These processes are also referred to as direct digital manufacturing or solid freeform fabrication and offer an alternative means for fabricating metal parts for the aerospace and medical implant industries. Dr. Beuth and his students perform analyses to predict melt pool size and residual stress for these processes, presenting results in the form of “process maps” that process development researchers can use directly. Through collaborations with Prof. Nathan Klingbeil of Wright State University, process mapping methods have been extended to consider microstructure control and means for integrated control of melt pool geometry and microstructure. This research is being performed with manufacturing and materials researchers at other universities, aerospace companies and NASA.
