Finite element analysis of the spherical indentation of transversely isotropic piezoelectric materials
Finite element analysis was used to analyze the indentation deformation of
a transversely isotropic piezoelectric material (PZT-4) by a rigid spherical
indenter. Three cases were considered in the analysis, which included (a)
the indentation by an insulating indenter, (b) the indentation by a conducting
indenter and (c) the indentation of the piezoelectric material with equal electric
potential on the top surface. The indentation load was found to be proportional
