Finite element simulation of the effect of electric boundary conditions on the spherical indentation of transversely isotropic p
Finite element simulation was used to analyze the effect of electric boundary conditions on the
indentation deformation of a transversely isotropic piezoelectric film with the contact radius
much larger than the film thickness. Six different combinations of electric boundary
conditions were used. The simulation results showed that the indentation load is proportional
to the square of the indentation depth and the indentation-induced electric potential at the

Contact deformation can cause local damage of mechanical structures and lead to structural failure
of mechanical devices. In this work, we use the finite element method to analyze the indentation-
induced delamination of a film-substrate structure and the critical tensile stress as the criterion to
determine local delamination on the interface between the film and the substrate. The simulation
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
The effect of an electric current on the nanoindentation behavior of tin
Electrical–thermal–mechanical interactions determine the reliability and performance of microelectromechanical devices and systems.
Using the nanoindentation technique the effect of an electric current on the indentation deformation of Sn strips was studied for an
indentation load in the range 50–200 lN. During the indentation an electric current density in the range 993.05–4087.89 A cm2
was
passed through the Sn strips, which introduced electrical–thermal–mechanical interactions. The experimental results showed that the
Finite-Element Analysis of Current-Induced Thermal Stress n a Conducting Sphere
Understanding the electrothermal-mechanical behavior of electronic inter-
connects is of practical importance in improving the structural reliability of
electronic devices. In this work, we use the finite-element method to analyze
the Joule-heating-induced thermomechanical deformation of a metallic sphere
that is sandwiched between two rigid plates. The deformation behavior of the
sphere is elastic–perfectly plastic with Young’s modulus and yield stress
decreasing with temperature. The mechanical stresses created by Joule
