To measure, confirm, and secure the reliability as regards the bonded joint holding strength at the plate-to-plate interface of the stainless-clad steel plate used as the hull structural material for chemical tankers, the authors devised and implemented a new fracture toughness tests as herein introduced. Selecting stainless-clad steel plates (SUS 316L+MS, SUS 317L+MS, and SUS 317LN+HT50) for their study, the authors performed JIS (Japanese Industrial Standard)-specified tests and the newly devised fracture toughness tests as follows. (1) JIS G0601-specified shear strength test and ram tensile test were performed, to determine the shear strength and ram tensile strength at the plate-to-plate interface of each of the stainless-clad steel plates. (2) The newly devised fracture toughness test methods were used in performing the cruciform welded joint tensile test, center-notched flat plate tensile test, and compact tension test using each of the stainless-clad steel plates, to positively determine the fracture toughness at the plate-to-plate interface in welded joint.
