| 摘要 |
<p>The present invention relates to a method for measuring the fine mechanical behaviour of the joints of rough interfaces connected by means of adhesives, generating interphases between the different elementary layers of a multiple material and a substrate or another multiple material bonded together. This method is characterised in that two-face double-bonding adhesive pieces (3, 11) are interposed between the faces of the multiple material (2) and those of the other substrate piece (1) or multiple material which are to be joined together by bonding, the two pieces (2, 1) bonded by means of the two-face adhesive pieces are subjected to mechanical stress, and strain gauges (j1, j2...jn) connected to a strain-gauge device (14) are used to measure the surface deformation occurring as a result of the strains in the various two-phase adhesive pieces under the effect of the mechanical stress. <IMAGE></p> |
