President, Wyoming Test Fixtures Inc. Unlike metals and plastics, for which tensile and compressive properties are the same or very similar, unidirectional composites exhibit significantly different ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

This image shows a representative cement micropillar sample imaged by scanning electron microscope. Samples like this one are key to the use of a 'micropillar compression' technique to characterize ...

President, Wyoming Test Fixtures Inc. Because composite structures are subjected to flexural loading in typical applications, it is not surprising that flexure testing of composites is commonly ...

Parts used in aircraft engines, power plants, and other high-temperature machines must survive extreme stress for long ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...

People tend to spend, on average, several hours a day sitting on couches, chairs, and car seats, as well as considerable time on mattresses every night. Polyurethane foam plays a major role in ...
