Shape and topology optimization for variational inequalities with pointwise boundary observation
Cornel Marius Murea, Dan Tiba
We study optimal design problems involving variational inequalities with unilateral conditions in the domain and pointwise boundary observation. We use regularizing and penalizatio…
Topology optimization and boundary observation for clamped plates
Cornel Marius Murea, Dan Tiba
We indicate a new approach to the optimization of the clamped plates with holes. It is based on the use of Hamiltonian systems and the penalization of the performance index. The al…
Penalization of stationary Navier-Stokes equations and applications in topology optimization
Cornel Marius Murea, Dan Tiba
We consider the steady Navier-Stokes system with mixed boundary conditions, in subdomains of a holdall domain. We study, via the penalization method, its approximation properties.…
Periodic Hamiltonian systems in shape optimization problems with Neumann boundary conditions
Cornel Marius Murea, Dan Tiba
The recent approach based on Hamiltonian systems and the implicit parametri\-za\-tion theorem, provides a general fixed domain approximation method in shape optimization problems,…
Implicit parametrizations in shape optimization: boundary observation
Cornel Marius Murea, Dan Tiba
We present first a brief review of the existing literature on shape optimization, stressing the recent use of Hamiltonian systems in topology optimization. In the second section, w…
Topological optimization and minimal compliance in linear elasticity
Cornel Marius Murea, Dan Tiba
We investigate a fixed domain approach in shape optimization, using a regularization of the Heaviside function both in the cost functional and in the state system. We consider the…
