概要

論文の詳細を見る
Metallic hollow sphere structure (MHS structure) is one of ultra-light porous metals. Applying the ultra-light structure to car parts has a possibility to save the fuel consumption because car body can be lightened without reducing the rigidity and the performance of absorbing collision energy. In this research, to estimate the performance of MHS structure, deformation behaviour of single MHS and the structure are examined by carrying out uniaxial compression test and bending test. In the compression test, plateau stress appears for the structure of low density. MHS diameter, shell thickness and carbon content have great influences to the magnitude of plateau stress and the increasing rate of stress with increase of density. In bending test, MHS structure has a weak point for tensile stress.
