内容説明

Mechanical engineering, an engineering discipline born of the needs of the industrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of productivity and competitiveness that require engineering solutions, among oth ers. The Mechanical Engineering Series features graduate texts and research monographs, intended to address the need for information in contemporary areas of mechanical engineering. The series is conceived as a comprehensive one the will cover a broad range of concentrations important to mechanical engineering graduate education and research. We are fortunate to have a distinguished roster of consulting editors, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the first page of the volume. The areas of concentration are applied mechanics, biomechanics, computational mechanics, dynamic systems and control, energetics, mechanics of materials, processing, thermal science, and tribology. Professor Winer, the consulting editor for applied mechanics and tribology, and I are pleased to present this volume of the series: High Sensitivity Moire: Experimental Analysis for Mechanics and Materials by Professor Post, Dr. Han and Dr. Ifju. The selection of this volume underscores again the interest of the Mechanical Engineering Series to provide our readers with topical monographs as well as graduate texts."

内容説明

Moire patterns (which form when two regular patterns of comparable frequency interfere) are sensitive indicators of changes of shape as objects rotate, heat up, or are otherwise affected by external forces. Applications include non-destructive testing and evaluation, and quality and process control. This text explains the theory and practice of physical measurements by high-sensitivity moire - principally moire interferometry, focusing on the mechanics and micromechanics of materials and structural elements. Moire interferometry is unique in providing maps of in-plane displacements from which can be derived normal and shear strains. Typical moire sensitivities are on the order of 2-4 fringes per fm displacement, but sensitivities of 17 nm per fringe contour can be reached. The applications discussed include: advanced composite materials, thermal stresses, electronic packaging, fracture, metallurgy, time-dependence, and strain gage calibration. The methods discussed in the text can be applied for whole-field measurements on nearly solid and solid bodies.
