Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

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 ...

Compression testing is used to determine how a product or material reacts when it is compressed, squashed, crushed or flattened by measuring fundamental parameters that determine the specimen behavior ...

Some more input from CalStar on their pending entry into the building materials market. I had asked about who set the standards for what is a "brick." The answer from CalStar: "ASTM is not the ...
