Compression failure of a timber block parallel to the grain


  • Material
  • Dimensions
    540mm x 90mm x 90mm
  • Design Criteria
    Designed for compression failure
  • Ultimate Load

This video shows the compression failure of a Class CL28 softwood timber block loaded parallel to the grain.

Learning Outcomes:

Viewers will gain an improved understanding of:

  • The strength properties of timber
  • The influence of grain orientation on sample strength

The specimen is placed between steel plattens which are then pushed together subjecting the block to a compression force. Failure occurs due to buckling of individual fibres forming the sample.

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.
