1. APPLICATION OF OPTICAL METHOD IN MEASURING MECHANICAL VIBRATIONS IN A CANTILEVER BEAM
ABSTRACT The pertinent literature discloses a family of optical profile measuring techniques highlighting the moiré methods. The Moiré technique is based on the interference of two superimposed optical grids which produce fringe patterns which can be processed to analyze the DYNAMIC MEASUREMENT IN MATERIALS mechanical behavior. The goal of this research is

2. Extensiometria óptica por Moiré geométrico digital para anãlise de tensões no plano / Optical extensometry by digital geometric Moiré for in-plane stress analysis
The study of the behavior of building structures pass through the determination of the strain and stresses to evaluate the level of local and global security against the active actions. In the last years in Brazil, the extensometers have been commonly used to measure the strain at a specific single point. The optical extensometry presents itself as an altern

4. Aplicação de técnica óptica no estudo da distribuição de tensões em modelos reduzidos de feixe de toras e peças serradas / Use of optical techniques applied on stress distribution study of reduced bundle log models and sawn pieces
A silvicultura ocupa a segunda posição no agronegócio brasileiro, exibindo grande importância econômica e social para o país. As atividades econômicas associadas ao reflorestamento enfrentam diversos obstáculos internos e externos, os quais se contrapõem ao crescimento desse setor no país. Nesse sentido, o transporte de madeira se torna um fator de

6. Moire assisted vibrational analysis of a cantelever beam : a case study / Analise vibracional de viga engastada utilizando a tecnica de moire : um estudo de caso
Vibration phenomena are of common occurrence in mechanics, generally associated to structural members as well as to machine elements. Particularly, in the field of agricultural engineering, vibration comes also associated to vegetable bruising during field operations, which clearly includes harvesting, transportation and processing. The selection of a simple

7. The Shadow Moiré method using the phase shifting technique and digital image processing: computational implementation and application to the 3D-reconstruction of a buckled plate
The Shadow Moiré fringe patterns are level lines of equal depth generated by interference between a master grid and its shadow projected on the surface. In simplistic approach, the minimum error is about the order of the master grid pitch, that is, always larger than 0,1 mm, resulting in an experimental technique of low precision. The use of a phase shift i
