Correlación de los resultados de impacto o tenacidad de 16 maderas mexicanas utilizando dos métodos de prueba

摘要: The wood impact bending resistance is considered an important mechanical property, mainly to determine the suitability of woods be used for tool hammers or sport goods, such as pistol handles, base ball bats and other uses where it would a need absorb disperse energy during impact. There are several test methods shock resistance, among those in Mexico toughness based on ASTM D143  standard (ASTM, 1999) Impact dynamic flexure test, NF B51-009 (AFN, 1942). Each method produces values different units. In order find correlation between results from these two allow comparison homogenization data already published Mexican testing program 16 was carried out. Test were performed green dry conditions both methods. An equation simple regression linear analysis obtained comparing sets results. will help wide scope knowledge properties woods.
