Extract

Howard suggested that the shear stiffness of a beam in bending could be more expeditiously determined by using the five point loading system.

Grayley reviewed the accuracy and speed of various methods of finding the shear stiffness of sandwich beams and showed that five point loading compared favourably on all counts with three point loading, four point loading, and with block shear tests.

The RAeS Data Unit gave a description of an experimental method of determining the shear and flexural stiffnesses of a sandwich material, based on Howard's work.
