... revealed cracks along the inner surface of the tubes, some of which had propagated through the thickness of the wall. Cracks emanating from weld toes were also visible. Based on their observations, investigators concluded that the tubes were subjected to excessive flexural load, causing cracks due to...

... flexure tests Flexure testing is covered in ASTM D 790 (three-point loading) and ASTM D 6272 (four-point loading). The specimen length is dependent on the thickness. A span-to-thickness ratio of 16 to 1 is recommended if the ratio of tensile strength to shear strength is less than eight to one. The...

... Abstract Ceramics normally have high melting temperatures, excellent chemical stability and, due to the absence of conduction electrons, tend to be good electrical and thermal insulators. They are also inherently hard and brittle, and when loaded in tension, have almost no tolerance for flaws...
