The part where a metallic material is connected to the composite material increases by such circumstances, and how a structural integrity in such a place is secured becomes an important problem. From the point of view, a principle of a method to monitor the mechanical and damage behaviors using axial strain in fastener bolt was proposed. In this paper, we actually made the fastener with an optical fiber sensor embedded in the shank of a titanium bolt, and applied it to the composite/titanium mechanical shear joint specimens to prove the function of it through the tensile tests. The results are summarized as follows; (1) proposed monitoring method is well available to monitor the load transfer mode around the fastener hole, (2) we can detect the damage by the change of inclination in the relationship between load and axial strain measured by the fastener bolt, and (3) it was shown that the early stage of damage of composites around the fastener hole can be detected by using the fastener bolt.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
