Bending of beams with bisymmetrical cross sections under non-uniformly distributed load: analytical and numerical-FEM studies

Free flexural vibrations of homogeneous beams with symmetrically variable depths

“…Magnucki et al [14] presented simply supported beams subjected to non-uniformly distributed loads. Shapes of bisymmetrical cross sections of the beams were expressed by special functions.…”

“…Taking into account the papers [14], the shape of the bisymmetrical cross section of these beams is assumed as shown in Fig. 3.…”
