13. THERMODYNAMIC NONEXTENSIVITY, DISCRETE SCALE INVARIANCE AND ELASTOPLASTICITY: A STUDY OF A SELF-ORGANIZED CRITICAL GEOMECHANICAL NUMERICAL MODEL / NÃO-EXTENSIVIDADE TERMODINÂMICA, INVARIÂNCIA DISCRETA DE ESCALA E ELASTO-PLASTICIDADE: ESTUDO NUMÉRICO DE UM MODELO GEOMECÂNICO AUTO-ORGANIZADO CRITICAMENTE
This thesis aims at applying new concepts from solid state physics and statistical mechanics - chaos theory and fractal geometry - to the study of nonlinear dynamic systems. More precisely, it deals with a two-dimensional continuum elastoplastic Mohr-Coulomb model, commonly used to simulate pressure-sensitive materials (e.g., soils, rocks and concrete) subje

14. APLICACIÓN DE ELEMENTOS FINITOS DE INTERFACE A MODELOS DE MODOS MIXTOS DE FISURAS / MODELING OF MIXED MODE CRACKS IN MASONRY STRUCTURES USING INTERFACE FINITE ELEMENTS / APLICAÇÃO DE ELEMENTOS FINITOS DE INTERFACE À MODELAGEM DE MODOS MISTOS DE FISSURAÇÃO
Since masonry is a widely employed material, it is fundamental to better characterize its structural performance and extend its use beyond functional applications (separation of environments). In this work a finite element model for masonry structures is presented. By using a sophisticated numerical tool based on the finite element method, associated to suit
