Let us take the example of the cantilever beam. Bending stress is a more specific type of normal stress. A plane running through the centroid forms the neutral axis – there is no stress or strain along the neutral axis. Consider the case where we replace our square cross-section in ANSYS with an I-shaped cross-section that is taller, has a lower cross-sectional area and the same moment of inertia. If more than one point load and/or uniform load are acting on a cantilever beam - the resulting maximum moment at the fixed end A and the resulting maximum deflection at end B can be calculated by summarizing the maximum moment in A and maximum deflection in B for each point and/or uniform load. Check Your Understanding. • Bending Moments • Bending Stress • Shear Stress • Direct Tensile Stress • Von Mises Stress Consider a cantilever circular rod 200 mm long and 4. When a beam experiences load like that shown in figure one the top fibers of the beam undergo a normal compressive stress. While bending moment is the algebraic sum of moments about the centroidal axis of any selected section of all the loads acting up to the section. Failure due to Shear in the Web usually takes the form of buckling brought about by the Compressive Stresses on planes at 45 degrees to the transverse section.
