This video shows the bending failure of a simply supported, Class C24 softwood beam arranged with the grain parallel to the beam axis. The test specimen is free of defects.
Viewers will gain an improved understanding of:
- The strength properties of timber
- The influence of grain orientation on strength
The beam is subjected to four-point bending. Failure occurs suddenly, with brittle fracture of the wood fibres occurring in the tension zone of the beam.
Structures expert, Doctor Christian Malaga-Chuquitaype of Imperial College, London narrates this video. Doctor Malaga-Chuquitaype is a Lecturer and Assistant Professor in the Structures Section at Imperial College’s Department of Civil Engineering.
