The present work describes a multiscale methodology which has been developed for modeling of impact damage in the laminated composite structures. The methodology employs the High Fidelity Generalized Method of Cells (HFGMC) micromechanical model for the prediction of the local stress and strain fields, within the representative unit cell of the unidirectional composite material. The Mixed Mode ...

The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures. Modeling on the micro-level has enabled insight into the underlying physical processes which lead to homogenized properties of the macro-scale material. In this work, micromechanical analysis has been performed by application of the High Fidelity Generali...

The micromechanical silicon resonant accelerometer has attracted considerable attention in the research and development of high-precision MEMS accelerometers because of its output of quasi-digital signals, high sensitivity, high resolution, wide dynamic range, anti-interference capacity and good stability. Because of the mismatching thermal expansion coefficients of silicon and glass, the micro...

The present paper deals with a micromechanical model of interface able to couple the damage (micro-crack) evolution, the non-penetration conditions (Signorini equations) and the friction effect (Coulomb’s law). At a typical point of the interface, a Representative Volume Element (RVE) is considered; it is characterized by the presence of two different materials and by a microcrack evolving alon...

In this paper, micromechanical constitutive models are developed to predict the tensile and fatigue behavior of fiber-reinforced ceramic-matrix composites (CMCs) considering matrix fragmentation closure. Damage fragmentation, interface debonding, fiber’s failure considered in analysis response, closure, debonding repeated sliding hysteresis response. Relationships between established. Experimen...

Bone is a hierarchically organized material, characterized by an astonishing variability and diversity. Bone replacement or biomaterials are critical components in artificial organs, and they are also used as scaffolds in tissue engineering. The aim of this thesis is the prediction of the strength of bone and bone replacement materials, from their composition and microstructure, by means of mul...
