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.
