Multiple speckle diffusing wave spectroscopy (MSDWS) can be applied to measure spatially heterogeneous mechanical behavior in soft solids, with high sensitivity deformation and both spatial temporal resolution. In this paper, we discuss the mathematical approach behind quantification of rate from MSDWS data provide guidelines for optimizing selection experimental parameters measurements. After ...

PURPOSE The debonding load of heat-activated polymethylmethacrylate (PMMA) denture base resin material to a nickel-chromium-beryllium (Ni-Cr-Be) alloy conditioned by three different surface treatments and utilizing two different commercial bonding systems was investigated. MATERIALS AND METHODS Denture resin (Lucitone-199) was bonded to Ni-Cr-Be alloy specimens treated with Metal Primer II, t...

The behavior of a thin curved hyperelastic film bonded to a fixed substrate is described by an energy composed of a nonlinearly hyperelastic energy term and a debonding interfacial energy term. We compute the Γ-limit of this energy under a noninterpenetration constraint that prohibits penetration of the film into the substrate without excluding contact between them.

The wear resistance mechanisms of a silicon carbide (SiC) paticulate reinforced Al–Li alloy composite at 250°C by a pyramidal indenter have been studied. It is found that the subsurface damages that control the wear resistance are: generation of dislocations and cracks in the SiC particles, interface debonding between matrix and reinforcements and plastic deformation of the matrix. © 1998 Elsev...

Acoustic emission monitoring is a useful technique to deal with detection and identification of damage in composite materials. Over the last few years, through intelligent signal processing was particularly emphasized. Data-driven models are developed predict remaining lifetime. Finite elements modeling (FEM) used simulate AE signals due fiber break fiber/matrix debonding model carbon thereby b...
