... sensitive than the stiffness in the studied range. The results for the slider acceleration show similar phenomena on the contact force. After applying the genetic algorithm, the optimal point is found to have a material stiffness coefficient of 3.4 × 10 +4 N/m 1.5 and a radial clearance size of 0.05 mm...

... and combined nonlinearities. Once the location and the type of nonlinearity are determined, a genetic algorithm based optimization is used to extract the actual values of the nonlinear parameters. The method developed allows simultaneous identification of one or more types of nonlinearity at any given DOF...

... appropriate topology can be extracted from this ground structure by means of gradient-based optimization algorithms. In the second approach, a genetic algorithm is used to solve the intrinsically combinatorial problem of topology synthesis. Along with several examples, both approaches are explained...
