Title in Portuguese
Estudo da solicitação de compressão normal às fibras da madeira
Keywords in Portuguese
Madeira - compressão normal
Madeira - propriedades mecânicas
Abstract in Portuguese
Este trabalho apresenta um estudo teórico e experimental a respeito da solicitação de compressão normal às fibras da madeira, para a qual não é previsto ensaio para caracterização, atualmente, na NBR-6230 (Ensaios físicos e mecânicos de madeiras). Foram abordados aspectos referentes à geometria do corpo-de-prova, velocidade de aplicação de carga, direção do carregamento em relação aos anéis de crescimento e condições de umidade. Com base nos resultados obtidos, é proposto método de ensaio para caracterização da madeira solicitada por compressão normal às fibras.
Title in English
Strength and stiffness of wood in compression perpendicular to the grain
Keywords in English
Wood - compression perpendicular
Wood - mechanical properties
Abstract in English
This work presents an experimental study about compression perpendicular to the grain in wood, for which characterization test is not indicated by NBR-6230 (Physical and mechanical test in wood). Several points were discussed: specimen geometry, speed of testing, direction of loading referred to the growth rings and moisture conditions. Based on the experimental data, a testing procedure is proposed in order to be employed in wood characterization in compression perpendicular to the grain.
