Homework Help: Engineering question, strength of materials

  1. Jan 19, 2010 #1
    in general, do ductile matreials fail due to shear or tensile stress

    i think that my lecturer said that brittle materials (such as concrete) will fail due to a low maximum shearing stress therefore breaking at 45 degrees in axial loading, and ductile materials have low tensile stress leaving a flat 180 degree break, but i read somewhere that it is the opposite, could someone clear this up for me

    You misremembered what your lecturer said, or that person was wrong. Ductile materials fail in shear.
