Abstract

The presentation is aimed to cover areas related to modeling of material behaviour using different numerical schemes. Special emphasis is laid on homogenization procedures and multi- scale approaches that include inelastic microstructural deformations and development of inter- [...]

Abstract

One of the most important engineering tasks over the years has been the design
and manufacture of increasingly sophisticated structural materials as a result of the
requirements related to the technological progress. In the last decades, the growing
needs for improved [...]

Abstract

The present work is concerned with the application of projection-based,
model reduction techniques to the ecient solution of the cell equilibrium
equation appearing in (otherwise prohibitively costly) two-scale, computational
homogenization problems. The main original [...]

Abstract

This work presents a two-scale homogenization procedure to analyze three dimension composite structures by FEM. The theory implemented is compared with other micro-structural formulations: micro models and serial parallel mixing theory, in terms of result accuracy and computational [...]

Abstract

The paper reports on the homogenization based modelling of fluid saturated poroelastic materials containing locally controlable piezoelectric (PZ) actuators. This option provides metamaterial properties which enable to convert the electric power into the fluid transport due to [...]

Abstract

Biot's theory of coupled mechanical-transport behavior of porous materials is applied in the framework of discrete mesoscale modeling. The contribution presents asymptotic expansion homogenization of the discrete poromechanical model. The macroscale becomes homogeneous and continuous [...]

Abstract

Multiscale structural models based on the coupling of a zigzag kinematics and a cohesive crack approach have been recently formulated to analyze the response of shear deformable layered structures with imperfect interfaces and describe progressive delamination fracture (Massabò, [...]

Abstract

In this study, resin permeability of plain-woven composites is analyzed using a three-scale homogenization method. To this end, the three-scale homogenization method is developed to analyze the resin flow through both the structures of fiber bundles and the inside of fiber bundles, [...]
