..., as in the Charpy V-notch specimen. The same testing machine can be used for both tests; however, the specimen geometry and computation of the impact toughness is different. The impact tester consists of a heavy pendulum that strikes the specimen at the bottom of its arch, where both the velocity and kinetic energy...

... that increase their yield strength will decrease their ductility. People who have worked metals know this, because heavily work-hardened metals often break easily. A familiar example of this behavior is the commonly used method of breaking a wire by bending it back and forth many times. Fig. 5.3 Increase...

... in the late 1800s. The earliest equipment used manual methods, such as hand cranks, to apply the load. In 1890, Tinius Olsen was granted a patent on the “Little Giant,” a hand-cranked, 180 kN (40,000 lbf) capacity testing machine. In 1891, Olsen produced the first autographic machine capable of producing...

In this case, the press drive is in “pendulum” mode; that is, instead of making a total revolution in one direction, the drive shaft rotates back and forth. By decreasing the tool impact speed while reducing the cycle time, it is also claimed that tool life can...
