Chat Online### Constrained and Unconstrained Optimization Formulations

In this work two numerical methodologies are proposed for the solution of unilateral contact problems between a structural member (beam or arch) and an elastic foundation. In the first approach the finite element method is used to discretize the structure and elastic foundation and the contact problem is formulated as a constrained optimization problem.

Chat Online### An Optimization Approach to Elastic Inverse ProblemsDRS

Imaging the elastic modulus distributions of soft tissues requires the solution of an elastic inverse problem. A typical approach to formulating this inverse problem is as an optimization problem. We consider in particular formulating this inverse problem as a constrained optimization problem in which we minimize the objective functional (the data mismatch) with the partial differential

Chat Online### Topology optimization under thermo-elastic buckling

Nov 15 2016 · Here we consider a level-set approach that relies on the concept of topological sensitivity. Topological sensitivity analysis for thermo-elastic buckling is carried out via direct and adjoint formulations. Then an augmented Lagrangian formulation is presented that exploits these sensitivities to solve a buckling constrained problem.
