Bending failure of a softwood beam with a defect near the bottom: Materials Lab on-line

This video shows the bending failure of a simply supported, Class C24 softwood beam arranged with the grain parallel to the beam axis. In this test, the specimen has a defect (or knot) near the bottom of the beam. Learning Outcomes: Viewers will gain an improved understanding of: - The strength properties of timber - The influence of defects on strength The beam is subjected to four-point bending. As the test proceeds, cracks start to appear within the knot. Splitting failure eventually occurs above the k
