Optimization of rigid-plastic shallow curved beams
An optimization technique has been presented for shallow circular beams of a rigid-plastic material. The thickness of the beam is assumed to be piece-wise constant. Minimum weight designs have been established under the condition that the deflections of the beam of piece-wise constant thickness coincide with those of the reference beam of constant thickness. Calculations showed that about 10 % of the material could be saved making use of the design with one step in the thickness. When utilizing the designs with two steps 2-3 % of the material could be saved additionally. Subsequent increasing of the number of steps gives much less economy. It appeared that the exact and approximate expressions of the material volume lead to results close each other.
