Resumen
Bamboo is considered an important raw material in developing countries because its physical characteristics associate lightness with high mechanical resistance. However its behavior obtained from mechanical tests is not yet well defined. This research work had the objective of evaluating bamboo (Guadua angustifolia) testing specimens under simple uniaxial compression loading. Shadow moiré optical methods had been employed to generate deformation mapping as function of knots (0, 1 or 2). Obtained results indicate that the technique is well adequate in generating iso-deformation contour lines in bamboo specimens. 9 3 309 322 Cloud, G., (1998) Optical method of engineering analysis, , Cambridge University Press, Cambridge Hu, Q. 2001. 3-D Shape measurement techniques. http://www.sinc.sunysb.edu/Stu/qhu / Chapterl.htm〉, 06/09/2001Malacara, D., (1992) Optical Shop Testing, , John Wiley & Sons, New York Pisarev, V.S., Balalov, V.V., A role of fringe patterns catalogue in the course of interferometrically based determination of residual stresses by the hole drilling method (2004) Optics and Laser in Engineering, 41, pp. 411-462. , London Post, D., Han, B., Ifju, P., (1994) High Sensitivity Moiré, , Springer, New York Saleh, B.E.A., Teich, M.C., (1991) Fundamentals of Photonics, , John Wiley & Sons, New York Takasaki, H., Moiré topography (1970) Applied Optics, 9 (6), pp. 1457-1462
