Abstract
A spring supported lower clamper for direct tensile test, comprising a lower connection member, a lower end cap for holding a sample, a lower chain for connecting the lower connection member with the lower end cap, and spring-type supporting provisions for supporting a broken-apart lower part of the sample formed during the tensile test and the lower end cap. During the tensile test, the sample, the lower end cap and the lower chain are supported by the spring-type supporting provisions. Thus the sample can be prevented from being broken abruptly when a tensile force in the sample reaches its maximum level, and the mechanical behavior after the maximum tensile force is reached can be measured.
