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.

In my January 2024 column, I reported on a new ASTM test method for use in assessing the damage tolerance of sandwich composites under compression loading: the sandwich compression-after-impact (CAI) ...

Recent reports in Europe and the United States raise concern about the potential negative impact of gene patents on the freedom to operate of diagnosticians and on the access of patients to genetic ...

During the late 1960s and most of the 1970s, the composites industry was absorbing the impact of what was then the recent introduction of carbon fiber. The resulting composites exhibited both high ...

Measuring how materials respond to different deformation speeds is imperfect, leaving gaps and uncertainties across strain rates. A single, self-consistent method to measure hardness across 11 orders ...

This video demonstrates an Izod impact test performed on a plastic specimen using CEAST 9050 impact pendulum from Instron. ASTM D256 is a standard test method for determining the Izod pendulum impact ...

The Institute of Structures and Design at the German Aerospace Center (DLR) in Stuttgart has been working on crashworthiness and high-speed impact for more than 30 years. Building upon these ...

Southwest Research Institute (SwRI) has expanded and advanced a ballistic resistance testing technique, the Laser-Induced Particle Impact Test (LIPIT), previously limited to using microscopic ...
