Finite Element Analysis Of The Contact Deformation Of Piezoelectric Materials, Ming Liu
Theses and Dissertations--Chemical and Materials Engineering
Piezoelectric materials in the forms of both bulk and thin-film have been widely used as actuators and sensors due to their electromechanical coupling. The characterization of piezoelectric materials plays an important role in determining device performance and reliability. Instrumented indentation is a promising method for probing mechanical as well as electrical properties of piezoelectric materials.
The use of instrumented indentation to characterize the properties of piezoelectric materials requires analytical relations. Finite element methods are used to analyze the indentation of piezoelectric materials under different mechanical and electrical boundary conditions.
For indentation of a piezoelectric half space, a three-dimensional finite element ...
