Scalar damage model for concrete without explicit evolution law
Josko Ozbolt, Sergey Ananiev
Based on the fact that for an isotropic material model the elastic predictor and the projected stress tensors have the same eigenvectors, it is shown that the scalar damage can be…
Plastic-damage model for concrete in principal directions
Sergey Ananiev, Josko Ozbolt
In the present paper a plastic-damage model for concrete is discussed. Based on the fact that for isotropic materials the elastic trial stress and the projected plastic stress stat…
Application of the equal dissipation rate principle to automatic generation of strut-and-tie models
Balthasar Novak, Sergey Ananiev
This work presents an extended formulation of maximal stiffness design, within the framework of the topology optimization. The mathematical formulation of the optimization problem…
On analogy between transition to turbulence in fluids and plasticity in solids
Sergey Ananiev
The subject of this work is the instability mechanism of simple shear flows, like Hagen-Poiseuille pipe flow, which is a long-standing problem in fluid mechanics [1,2]. A possible…
On Equivalence between Optimality Criteria and Projected Gradient Methods with Application to Topology Optimization Problem
Sergey Ananiev
The paper demonstrates the equivalence between the optimality criteria (OC) method, initially proposed by Bendsoe & Kikuchi for topology optimization problem, and the projected gra…
