The high stresses in the joints of chassis frames subject to torsion are estimated theoretically and confirmed by tests on photoelastic models. The joints considered are between channel section cross members welded or continuously attached to the webs of channel section side members. The detailed stress distribution in the side members has been estimated using classical plate theory to find the forces resisting the warping displacements of the cross members. Models of joints and a complete frame were made from channel section castings of birefringement material and coated with reflective material to allow the use of a reflection polariscope to analyse the stress distribution. The theoretical results were compared with the results from approximate theories as well as with the photoelastic test results.
