Abstract
The boundary element method is used for studying frictionless indentation response of piezoelectric (PE) films under spherical indenter (i.e. sphere) and circular cylindrical indenter (i.e. punch). An augmented Lagrangian formulation is employed to solve PE films of finite thickness under contact conditions. The methodology is validated by comparison with theoretical solutions presented in the literature for the two limiting cases: infinitely thick and infinitely thin PE films closed-form solutions. Furthermore, the formulation is applied to compute the indentation response of those cases in between.
