Thermomechanical Behavior of Functionally Graded Materials (FGM)
Abstract
This final report is to document a summary of Ph.D. Student, Mr. Steven Hudnut who was supported by this ASSERT Grant, working on design of Piezo Actuators with Functionally Graded Microstructure (FGM). Mr. Hudnut has achieved both analytical modeling of several FGM piezo-laminate actuators with aim of maximizing the bending displacement while minimizing the internal stress, thus enhancing its fatigue life. Mr. Hudnut designed a new laser displacement measurement apparatus by which the bending performance of bimorph and bimorph FGM piezo-actuators are characterized. He also contributed to the construction of lamination model for piezo laminated composites, as well as optimization of the FGM bimorph actuator mode of continuous piezo fibers.
