To help labs characterize the toughness of steel, a new software package allows analysis of instrumented Charpy tests, or Charpy tests augmented with strain gauges, in compliance with standards from ...

Charpy testing is a method for determining the relative impact strength of metals. It is also known as the Charpy V notch test. This testing method was developed in the 1940s by S.B. Russell and G.

At NPE 2015, Testing Machines Inc. of Newcastle, Del., will introduce a newly designed pendulum tester, Model 43-76, at Booth S12175. The device has a robust mechanical design that can easily be ...

A decade before an iceberg shattered the hull plates of the Titanic and half a century before a plague of brittle fractures started sinking Liberty ships during World War II, scientists in the United ...

The impact response of composite materials was of only minor interest prior to the introduction of carbon fiber in the mid-1960s. Before that time, the composites in use were primarily reinforced with ...

The main features of the Zwick roboTest I Charpy impact tester are outlined. These include the automatic sample loader, sample camera, environmental chamber and the impact tester. The testing sequence ...

These types of specimen tests are commonly used to determine the key properties of a material, such as tensile strength, Izod and Charpy impact strength, hardness, flammability, shrinkage and ...
