| Abstract: | The 3-D contact stress in bolted joint parts and its contact coverage are investigated ex-perimentally with the photoelastic method and the newly developed caustics method.Test re-sults obtained will provide useful data for the computation of the joint parts by the finite ele-ment method and the reliability analysis as well as for the design of the cylinder head of aninternal combustionn engine. |
