| Abstract: | Results reported in the literature for the behaviour of multi-bolt joints in composite materials can be contradictory, owing basically to the variation of the load distribution between the bolts. Therefore, the present investigation of the behaviour of two-bolt joints made from pultruded glass/polyester composite materials concentrates on the load distribution between the bolts. The results of this work show a tendency for the loads to equalize with increasing load. The achievement of full load redistribution has been found to depend on the amount of local deformation that can develop before the joint fails. |
