Exact closed-form solutions for the static analysis of multi-cracked gradient-elastic beams in bending

Display Omitted •Exact solutions derived for nonlocal multi-cracked Euler–Bernoulli beams in flexure.•Dirac’s deltas are used to model concentrated increases in the bending flexibility.•Finite jumps in the rotations’ profile of the beam are smoothed.•Effects of stress and strain gradient length scal...
