摘要： In a dissimilar material joint structure that joins together an anti vibration bar (first member) 14 and a end cap (second member) 15, which is a dissimilar metal material to the anti vibration bar 14, the anti vibration bar 14 is sandwiched by a plurality of end caps (second members) 151 and 152, and these respective end caps 151 and 152 are joined together by welding. Due to contraction of a weld material 153 welding the end caps 151 and 152, the anti vibration bar 14 is sandwiched between the end caps 151 and 152, whereby the anti vibration bar 14 and the end cap 15 are joined. Consequently, a thermal treatment for welding dissimilar metal materials is not required, and the welding operation can be carried out easily.

摘要： A reduction in cost and improvement in evaluation accuracy are achieved. Provided is an in-plane compressive strength evaluation device (10) that is provided with a memory unit (21) into which, when an in-plane compressive strength evaluation is actually performed using a test piece, an evaluation result related to the load and a displacement in the test piece is stored as first information; a first analysis unit (22) that obtains, by producing a structural model of a test piece and performing a simulation of the in-plane compressive strength evaluation, second information that is an evaluation result related to the load and a displacement of the structural model; an adjustment unit (23) that adjusts an elemental factor of the structural model that influences the in-plane compressive strength such that the second information approaches the first information; and a second analysis unit (24) that, in a state where the elemental factor used when the second information approaches the first information most closely is maintained, expands the structural model into the structural form of the actual tube support plate, and that performs the in-plane compressive strength evaluation using the expanded structural model.
