Modulus of elasticity and Poisson’s ratio of fiber-reinforced concrete in Colombia from ultrasonic pulse velocities. Non-destructive methods are already widely used to characterize different materials like wood, fibers, composites, concrete, and aluminum, for example ( Carrillo et al., 2019 CARRILLO, J., RAMIREZ, J., & LIZARAZO-MARRIAGA, J. In contrast, non-destructive methodologies perform tests without modifying the structure of the material, allowing its use after the test, seeking to make them more instinctive in obtaining data quickly and directly. However, these tests require preparation of a large number of test specimens, in addition to a long time to acquire the data. Rio de Janeiro, RJ: NBR 7190, 2011, 50p.), is widely used in scientific research. Associação Brasileira de Normas Técnicas - ABNT, 2011 ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS. Department of Agriculture, Forest Service, Forest Products Laboratory, 2010. In: Forest Products Laboratory Wood handbook: wood as an engineering material. This method already consolidated (American society for testing and materials - ASTM, 1994 Kretschmann, 2010 KRETSCHMANN, D. Philadelphia, PA: ASTM D143, 1994, 50p.) or other standards. Standard methods of testing small clear specimens of timber. Therefore, once the material is known, it is possible to make the best use of it and presume its behaviour under service.Īssays to characterize the mechanical behavior of wood may be performed in a conventional manner using the universal testing machine according to D143 ( American society for testing and materials - ASTM, 1994 AMERICAN SOCIETY FOR TESTING AND MATERIALS. When using a wood, it is necessary to understand its anisotropy, which represents a different behaviour as a function of its axes, when submitted to efforts ( Panshin and Zeeuw, 1980 PANSHIN, A. Wood is a versatile material whose mechanical properties are crucial to its most diverse uses.
