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 ...

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.

Armchair shopping on the internet and the advent of virtual reality imaging will soon change our lifestyle. Many products will be purchased from within our own living rooms and delivered directly to ...

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 ...

Due to the increase in the use of plastics, the formation of microplastics in the environment is rising. However, the impact of these tiny plastic particles is not yet included in environmental and ...
