Bending/flexure of beam structures SEN2MET Chapter #2, part 2 2 Upward bending moment M We will firstly regard slender beams: Cross section dimensions are small compared with the length of the beam Next, the beam material is linear-elastic: • Hook’s law applies Finally, plane cross-sections remains plane (i.e. pure bending: • No twisting of cross sectional planes • 2-D ( x,z ) mathematical problem Euler-Bernoulli bending theory applies In pure bending the beam undergoes a deformation in the x,z plane due to external bending moments M
