7.8: Plastic deformation during beam bending

Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. The transverse bending test is most frequently employed, in which a specimen having either a circular or rectangular cross-section is bent until fracture or yielding using a three-point flexural test te… Web1. Flexural failure in which cracks are mainly vertical in the middle third of the beam span. 2. Diagonal tension failure, this failure precipitates if the strength of the beam in diagonal tension is lower than its strength in flexure. 3. Shear compression failure in this case the beam has a small shear span/depth ratio of the magnitude of 1-2. ... indian army recruitment videos
