More Information
Summary:The invention provides a material testing machine. When a crosshead descends after a specimen is loaded, pins attached to link members contact seat surfaces formed on seat members, and then contact side walls of the seat surfaces. As the crosshead descends further, the pins contacting the seat surfaces press the seat members 31. This pressing force moves a pair of first slide members away from each other as guided by a first rail, and moves a pair of second slide members away from each other as guided by a second rail 24. Consequently, tension loads in biaxial directions perpendicular to each other are applied to the specimen gripped by four chucks 25.
