Abstract
Almost all products and structures have joint structures such as bolted, adhesive, solder or welded joints for productivity and maintenancebility. Many failure accidents or troubles occur on these joint structures, as the stress flow in these joint structures are complicated or many human manual work were intervened in manufacturing process. In this paper we review the strength evaluation technology or mechanical consideration for these joint structures based on the failure accident examples. Then we present new strength design methodology based on genuine mechanical analyses and production engineering aspects. And finally we present new CAE design tools, which will be suitable for on-site design engineers.
