Optimal periodic output feedback control: a continuous-time approach [PDF]

open access: yes, 2007
: This paper addresses the problem of optimal static output feedback control of linear periodic systems. The proposed approach, which allows to deal with both stable and unstable open loop systems, relies on a continuous-time formulation of the control ...

An interface-oriented data-driven scheme applying into eutectic patterns evolution

open access: yesMaterials & Design, 2022
Solid-liquid interface dynamics plays a crucial role in microstructure evolution during solidification. However, it is difficult to extract sufficient spatial information to describe the variation in the irregular and non-periodic solid-liquid interface ...

Evolutional Contact with Coulomb Friction on a Periodic Microstructure [PDF]

open access: yesPAMM, 2013
AbstractWe consider the elasticity problem in a heterogeneous domain with an ε‐periodic micro‐structure, ε ≪ 1, including a multiple micro‐contact in a simply connected matrix domain with inclusions completely surrounded by cracks, which do not connect the boundary, or a textile‐like material.

Damage as Gamma-limit of microfractures in anti-plane linearized elasticity [PDF]

open access: yes, 2008
A homogenization result is given for a material having brittle inclusions arranged in a periodic structure. <br/> According to the relation between the softness parameter and the size of the microstructure, three different limit models are ...

The analysis of localized effects in composites with periodic microstructure [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013
Several methods for the analysis of composite materials with periodic microstructure in which localized effects (such as concentrated loads, cracks and stationary/progressive damage) occur are resented. Owing to the loss of periodicity caused by these localized effects, it is no longer possible to identify and analyse a repeating unit cell that ...

On solving periodic Riccati equations [PDF]

open access: yes, 2008
Numerically reliable algorithms to compute the periodic non-negative definite stabilizing solutions of the periodic differential Riccati equation (PRDE) and discrete-time periodic Riccati equation (DPRE) are proposed. For the numerical solution of PRDEs,

A modular framework to obtain representative microstructural cells of additively manufactured parts

open access: yesJournal of Materials Research and Technology, 2022
The repeating nature of additive manufacturing (AM) translates into quasi-periodic repeating hierarchical microstructures, which vary depending on the working principle of the AM technology.

Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]

open access: yes, 2015
In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.

Efficiency of the Needle Probe Test for Evaluation of Thermal Conductivity of Composite Materials: Two-Scale Analysis

open access: yesStudia Geotechnica et Mechanica, 2014
The needle probe test, as a thermal conductivity measurement method, has become very popular in recent years. In the present study, the efficiency of this methodology, for the case of composite materials, is investigated based on the numerical ...
