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
Nano Puncture Resistance Using Nanoindentation
Traditional Puncture Tests are typically used to determine the penetration characteristics of a wide range of protective material such as films, foils or membrane. It is widely used in food and medical industries on applications ranging from food packaging to rubber gloves and needles. The test is preformed like that of a compressive test. A probe, with multiple tip selection, uses increasing load until material is penetrated and load is recorded at failure.

EXTENDED ABSTRACT SUBMISSION: Nanobrücken II: A Nanomechanical Testing Workshop, March 22-23, 2012, INM Saarbrücken, Germany
Dear Colleague:
You are cordially invited to attend Nanobrücken II: A Nanomechanical Testing Workshop, jointly presented by INM - Leibniz Institute for New Materials and Hysitron, Inc., with co-sponsorship from the JEOL company. This is the second workshop in the Nanobrücken series. The workshop's scope has been broadened, and the abstract submission deadline is now February 19, 2012.
Shot Peen Hardness With Nanoindentation
The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation, nanoindentation, will play a vital factor in achieving reliable and intended results.
Viscoelastic Analysis With Nanoindentation DMA
Viscoelasticity can be studied using Dynamic Mechanical Analysis (DMA) during Nanoindentation. By applying controlled oscillatory stress the resulting strain can easily be measured. An elastic material will have stress and strain in phase while a viscous-elastic material will have strain lagging stress. In many applications during quality control and R&D, it is important to reliably test this behavior.
Fellowships and Ph.D. position available: Analysis and modeling of the mechanical behavior of 3D nanoparticles superstructures
Colloidal nanocrystals (NCs) form a family of highly advanced building blocks suitable for large scale assembly of novel high-complexity 1D-to-3D superstructures. Their properties and inter-particle interactions, nowadays, can be highly controlled by tailoring their size, shape, composition and surface functionalization.
