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 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
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
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
Natural rubber (NR) is known to crystallize under strain (SIC) so that NR samples subjected to loading-unloading cycles exhibit hysteresis. A brief review of the numerous experiments conducted on this material is given. Detailed information on the microstructure is therefore available, particularly simultaneous measurements of stress versus elongation and
The 23rd International Congress of Theoretical and Applied Mechanics (ICTAM2012) will be held in Beijing, China, from 19 to 24 August, 2012. The Congress is hosted by The Chinese Society of Theoretical and Applied Mechanics (CSTAM).
The Congress venue is the China National Convention Center (CNCC) which is ideally located in the heart of the Olympic Green of Beijing, adjacent to the National Stadium (Bird’s Nest) and the National Aquatics Center (Water Cube).
A postdoctoral/research associate position is available in the area of computational modeling of granular materials at Rutgers University working under the supervision of Prof. Cuitino. Candidates with a strong background in computational mechanics of solids, interfacial mechanics, granular materials and computational methods are highly encouraged to apply.
