Lateral Force Microscope Calibration Using a Modified AFM Cantilever

February 19, 2017
Author(s)
Mark Reitsma
A proof-of-concept study is presented for a new force transducer and associated calibration method that provides a path for quantitative friction measurements using a Lateral Force Microscope. The transducer design is an Atomic Force Microscope (AFM)

Lifetime Prediction for Silicon Nitride

February 19, 2017
Author(s)
Sheldon M. Wiederhorn
This paper reviews lifetime prediction methodologies for high-temperature structural ceramics. The methodologies consider failure from subcritical crack growth at low temperatures, 800 C to 1000 C, and creep, or creep-rupture at high temperatures. The

Material Properties of a Sintered a-SiC

February 19, 2017
Author(s)
R G. Munro
A self-consistent, single-valued representation of the major physical, mechanical, and thermal properties of a sintered Α-SiC is presented. This comprehensive set of properties is achieved by focusing on a narrowly defined material specification in which

Materials Design for Biomechanical Layer Structures

February 19, 2017
Author(s)
Brian R. Lawn, Antonia Pajares, P Miranda, Y N. Deng
A survey of recent advances in the analysis of ceramic-based layer structures for biomechanial applications is presented. Data on model layer systems, facilitating development of explicit fracture mechanics relations for predicting critical loads to

Measurement Methods for Materials Properties: Elasticity

February 19, 2017
Author(s)
Sheldon M. Wiederhorn, Richard J. Fields
Elastic constants must be obtained by experiment methods. Materials are too complicated and theory of solids insufficiently sophisticated to obtain accurate theoretic determinations of elastic constants. Usually, simple static mechanical tests are used to

Mechanical Properties of Aluminum Nitride Substrates

February 19, 2017
Author(s)
Jay S. Wallace, Lin-Sien H. Lum
Aluminum nitride (AlN),because of its high thermal conductivity, is seeing increased use for heat management applications of semiconductor devices. With the likelihood of large mechanical stresses, both during fabrication as well as in service, mechanical

Mechanical Reliability and Life Prediction for Brittle Materials

February 19, 2017
Author(s)
Grady S. White, Lin-Sien H. Lum, Stephen W. Freiman
This chapter is intended to provide the reader with a general understanding of why brittle materials fail in a time-dependent manner in service and how to estimate the lifetimes that can be expected for such materials. In addition, we describe procedures

Model for Adhesion-Based Energy Dissipation During Friction

February 19, 2017
Author(s)
Michael Nosonovsky, Stephen M. Hsu
Adhesion plays a significant role in Nanoscale interfacial friction for basically non-adhesive surfaces (no chemical bonding). The adhesion forces are composed of van der Waals forces and the contact force from surface contact. The van der Waals forces are
