    A shave-joining method with induction system for heating the hole of the base-material is successfully developed for realization of the high productivity. Moreover, influencing factors of the shear strength of the shave-joint are experimentally investigated for joining of the disc of 2-5 mm thickness which are made of such different materials as medium carbon steel (S45C) and silicon nitride ceramics (Si3N4), with the cylinder with inner diameter of about 20 mm which are made of such base materials as aluminum (A1050), aluminum alloy (A5056) and mild steel (STKM13). The shear strength of the shave-joint increases uniformly with increasing induction-heating time or temperature until transformation and melting of the materials, and with increasing shaving depth up to 1.0 mm. The value obtained by the simple shave-joining is over a quater of the shear resistance of the base material and also remarkably improved by repeating the joinned parts for the similar metals.

  • A Simplified Method of Calculating Mode I Component of Delamination Energy Release Rate

    A simplified method of calculating mode I component of the energy release rate associated with the free-edge delamination crack growth in the anisotropic composite laminate is proposed. The method is based on the J-integral type conservation laws in combination with the simplified method formerly developed by the authors to calculate the asymptotic value of the total energy release rate for large delamination crack length. Numerical results are compared with those from the finite element analysis for laminates with several stacking sequences. Although the accuracy of the calculation scheme depends mainly upon the reference state of the quasimode I delamination used, the present method is still useful for the primary design survey for the delaminations of composite laminates.
