When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

As the name implies, the Short Beam Shear test subjects a beam to bending, just as flexural testing methods do, but the beam is very short relative to its thickness. For example, ASTM D 2344 1 ...

Concrete suppliers and contractors are sometimes accused of producing or placing low-strength concrete. While low-strength concrete does occasionally occur, many times reported cylinder strengths are ...

During the 1970s, fracture toughness testing of composite materials developed a very poor reputation, primarily due to failed attempts to directly adopt metals theory and corresponding test methods.
