Contour modification of elastic axisymmetric structures based on the finite element synthesis

Numerical examples of elastic axisymmetric structure shape modification to reduce and redistribute stresses by means of the structural synthesis technique based on that the objective design is sought to be close to the baseline one, are presented. Design variables are nodal coordinates of the finite elements along a contour. The objective response is both to reduce the elastic stress and to redistribute its concentration in the initial structure.
