Two Load Distribution Measurement Methods of Single-Lap Composite Joints

Abstract:

Load distribution is a precondition for strength predictions of multi-bolt composite joints and thus accurate load distribution measurement methods are required. Here two improved methods that strain gauge belts and improved instrumented fasteners are adopted to test the load distribution of single-lap three-bolt composite joints. Although the strain gauge belt can eliminate some errors induced by the manual mounting, it results in rather large errors relative to the theoretical spring model solution. In comparison with the strain gauge belt, the load transfer ratios obtained from improved instrumented fasteners are closer to the theoretical solutions and smaller errors can be obtained, which offers powerful evidence for the applicability of the improved instrumented fasteners to the load distribution measurement of single-lap multi-bolt composite joints.
