Investigation of the Effects of Environmental Fatigue on the Mechanical Properties of GFRP Composite Constituents Using NanoindentationAbstract
Background
Fatigue failure criteria for fibre reinforced polymer composites used in the design of marine structures are based on the micromechanical behaviour (e.g. stiffness properties) of their constituents. In the literature, there is a lack of information regarding the stiffness degrada... ...

Experimental Results of a Damage Detection Methodology using Variations in Modal Parameters
Experimental Mechanics - Tập 46 - Trang 441-451 - 2006
The present paper reports the results obtained by a methodology of damage detection in which combined EMA and FEM data are used to localise the damage on mechanical components. The utilized method uses the eigenvalues and eigenvectors obtained from FE modelling, compared with the eigenvalues obtained experimentally on damaged specimens. The method assumes a linear behaviour of the materials. First......

Estimation of Uncertainty for Contour Method Residual Stress Measurements
Experimental Mechanics - Tập 55 - Trang 577-585 - 2014
This paper describes a methodology for the estimation of measurement uncertainty for the contour method, where the contour method is an experimental technique for measuring a two-dimensional map of residual stress over a plane. Random error sources including the error arising from noise in displacement measurements and the smoothing of the displacement surfaces are accounted for in the uncertainty......
The Development of a High Rate Tensile Testing System for Micro Scaled Single Crystal Silicon Specimens
Experimental Mechanics - Tập 54 - Trang 413-419 - 2013
Structures have been built at micro scales with unique failure mechanisms that are not yet understood, in particular, under high-rate loading conditions. Consequently, microelectromechanical systems (MEMS) devices can suffer from inconsistent performance and insufficient reliability. This research aims to understand the failure mechanisms in micro-scaled specimens deforming at high rates. Single-c......
Simple optical processing of moiré-grating photographs
Experimental Mechanics - Tập 20 - Trang 265-272 - 1980
The three fundamental optical phenomena of diffraction, two-beam interference, and transformation by a lens form the basis of modern moiré strain-measurement techniques. The improved understanding of diffraction by superimposed gratings and optical spatial filtering leads to a general gain of freedom in designing moiré experiments. Benefits characteristic of refined but very simple optical-data-pr......
