The first time the stress test was carried out and repeated the material became less stiff and strong, but the team says that further compressions made very little difference.

第一次试验后材料表现不错，直至反复试验之后，材料的硬度和轻度都有所下降，但是小组人员说，再试验下去材料的变化也不会太大了。

Next, unloading-reloading cycles are repeated in constant loading rate test with Sanjome andesite and Inada granite; and unloading curves at many points along stress-strain curve are obtained.

其次，对三城目安山岩和稻田花岗岩在恒定速率下进行循环加载卸载试验，得到了应力—应变曲线上很多点处的卸载曲线。
