異材継手の界面強度に関する基礎的研究

抄録

Effects of specimen sizes and loading types on an interfacial strength of bonded dissimilar materials were investigated. The energy release rate, g, was used for estimating the strength.
Resin and steel were used for the dissimilar materials. The Implant type specimens were tested under both tension and torsion loading types. g-value was calculated by the finite element method (FEM).
The larger the diameter of the specimen is, the lower tensile and/or torsional strengthes is, in each loading type. However, as g-value almost shows constant value in each loading type, g-value becomes useful parameter for estimating an interfacial strength of the joint bonded dissimilar materials.
