薄板ばね特性試験機の試作

抄録

A cantilever type apparatus employed to examine the spring elastic limit, K_b of a steel plate with a thickness up to 0.1mm.
1) The K_b for specimens with thickness of 0.1mm and 0.2mm were comparable to the values obtained by the APT type machine at the test condition of L≈100t.
2) The K_b for ultra thin steel plates could be measured by the present testing machine as well.
