Shape optimization in contact problems with friction
Pathó, Róbert ; Knobloch, Petr (referee) ; Haslinger, Jaroslav (advisor)
In the present work we formulate a shape optimization problem for the 2D Signorini problem with given friction and a coefficient of friction which depends on the solution. The aim is to find an optimal contact part of an elastic body. A suitable set of admissible domains is given, among which the existence of an optimal one is established for a large class of cost functionals. The shape optimization problem is then approximated. Existence of discrete optimal shapes is proven and convergence analysis is done.
Optimization methods for inverse problems with energy norm
Hrtus, Rostislav ; Haslinger, Jaroslav ; Blaheta, Radim
The paper deals with the application of the energy norm in the inverse problem which is based on a minimization of a nonlinear least squares function. Three different parameter distribution examples are solved by the steepest descent, nonlinear conjugate gradient and Newton methods. Efficiency comparison is also presented.
