Deformation processing and the mechanical behavior of materials, with focus on sheet-metal formability, orthopedic and cardiovascular implants, powder,composites, and clad materials. Interaction of law and technology, standards, and risk management. Productivity and innovation.

Professor Piehler's materials research areas are physical and analytical modeling of deformation processing systems and performance evaluation of mechanically fabricated components and products. His policy research areas are in medical device risk management, engineering manpower utilization, plus productivity and innovation.

His materials research includes sheet metal formability, triaxial consolidation of powder compacts and composite materials, which facilitates consolidation and improves properties compared to those achieved by pure isostatic compaction. Other materials research focuses on fabrication and performance of surgical materials and devices, using in vivo tests designed to link prior processing with in vivo performance. Nondestructive testing procedures are developed to predict incipient failures. Risk-management and regulatory strategies are designed to respond to these performance evaluations.

His policy research has focused on the career paths of Japanese and American engineers, in order to understand how the generation and dissemination of technical information occurs in these two countries.

Professor Piehler is on several committees of the American Society for Testing and Materials (ASTM), including the Committee on Medical and Surgical Materials and Devices.
