SHEAR TEST RINGS

摘要

The present invention relates to shear test rings comprising: an upper shear ring including an upper frame and an upper ring formed to be coupled to the upper frame; a lower shear ring including a lower frame and a lower ring formed to be coupled to the lower frame; and a pin combining the upper shear ring and the lower shear ring. The upper shear ring and the lower shear ring are stacked on top of each other to be fixed by the pin. The upper frame and the lower frame have respective heat sources configured to keep temperatures of the upper ring and the lower ring constant.
