Optimal rigidity distribution of thin ribs in a bending plate under the minimality condition on the deformation energy (English)
0 references
The author proposes a method for optimal design of thin rigid ribs in bending plates, which is based on the minimization of deformation energy. Numerical results show that, in comparison with uniformly rigid ribs, ribs with optimal rigidity distribution lessen the maximal plate deflection and stress concentration. The proposed optimization is especially effective for point loads.
