Title

(EN) Adhesive Selection Method, Adhesion Complex, and Production Method for Adhesion Complex

Abstract

(EN)

In an adhesive selection method, test data is acquired by subjecting an adhesion complex, obtained by integrally bonding one material and an other material that are heterogeneous using an adhesive, to a shear test, in which a tensile shear load is applied to the adhesion complex in a direction that causes shear deformation in the adhesive, until adhesive failure takes place. Based on the test data, a plurality of two- or three-dimensional FEM analysis models of the adhesion complex with varied adhesives are constructed. On each of the analysis models, a simulation is performed in which a tensile shear load is applied. Based on the stresses and locations of the stresses generated in each of the analysis models in the course of the, the adhesive for binding one member made of the one material and the other member made of the other material is selected from among the adhesives.
