金属-セラミックス-高分子間の同材および異材間の新接合技術の効率的な開発のために有用なマルチ接合界面設計システムの開発を目的として、複雑現象を高速で解析可能な大次元問題高速解析法を開発し、本解析法を用いて、従来の構造解析ソフトでは困難あるいは不可能であった、発砲アルミニウムの力学特性や鋳造部品の熱変形の解析に成功するとともに、電磁シーム圧接法による鉄-アルミニウム合金接合体の接合性可否の主要因子を明らかにした

Metal-セラミックス-Efficient new joining technology between polymers of the same material and between different materials and efficient joint interface design The purpose of the calculation is the purpose of the calculation, the high-speed analysis of the complex phenomenon is possible, the high-speed analysis method of large-dimensional problems is the use of this analysis method, Structural analysis of the difficulty and impossibility of structural analysis, analysis of the mechanical properties of the mechanical properties of the manufactured parts, and the thermal deformation of the manufactured parts. The main factors for the success of the electromagnetic pressure connection method and the jointability of the alloy joints are as follows:
