We report on recent investigations into the mechanical properties of metallic micro-specimens deformed in tension and compression. We will focus on investigations using a custom test apparatus for in-situ focused ion beam and scanning electron micros

Biaxial principal strains were measured at the roots of notches in aluminum specimens with a laser-based interferometric technique. Interference patterns from three tiny indentations spaced 150 or 200 micrometers apart in an orthogonal pattern were m

The Neuber relation is widely used to compute elastoplastic stresses and strains at stress concentrations, but a newer relation has been developed by Glinka. Prediction of local strain response is important because low cycle, fatigue life models are
A laser interferometry crack tip opening displacement measurement technique has been developed and is described here. This interferometric displacement gage was used to measure displacements near the crack tip in flawed specimens. Measured displaceme

There are three main challenges in measuring the mechanical properties of specimens with minimum dimensions on the order of microns or less — preparation and handling, force application and measurement, and strain measurement. This is a brief overv

An overview is given of methods for testing thin-film tensile specimens of either MEMS materials or surface coatings. MEMS specimens are deposited in a final shape and need only to be released for testing, while specimens of coating materials must be

Polysilicon materials from three different suppliers were tested in tension to determine their Young’s modulus and strength. The modulus of polysilicon from Cronos was 158 ± 8 GPa and its strength 1.56 ± 0.25 GPa, and the material from Sandia Nat

The aim of this project was to carry out a fundamental study of the basic: Physics underlying the applications of gas and vapor bubbles in heat transfer systems, pumps, actuators, and other small-scale systems. Since these applications require a deta
