 · During determination of bending fatigue strength the specimen is subjected exclusively to alternating loading in order to obtain a mean value of zero between positive and negative loads of equal magnitude. As the greatest stresses occur on the surface of the specimen, the condition of the surface is of particular importance in this test method.

 · Bending strength or flexural strength is the maximum bearable bending stress at which the specimen fractures! The bending strength is also determined according to the bending equation ( 2 ), although in the state of fracture there is no longer a linear stress distribution due to plastic deformation!
