Resumo: This work deals with some Thermodynamics principles related to continuum media that are particularized to the Local State Method used in the formulation of damage models. Initially, some aspects of Continuum Damage Mechanics (CDM) are discussed, which is an applicable tool for macroscopic modelling of materials. In a general way, this paper intends to show the efficiency of constitutive models based on Thermodynamics principles, presenting a constitutive model applied to the analysis of reinforced concrete structures. To show the accuracy of the proposed formulation, the numerical results of a simply supported beam with different reinforcement rates are compared with its experimental data

Inicialmente, são apresentados alguns aspectos da Mecânica do Dano Contínuo, que se constitui numa ferramenta de grande aplicabilidade na modelagem macroscópica de materiais. Em seguida, o trabalho trata dos princípios da Termodinâmica dos Processos Irreversíveis. De maneira geral, o objetivo do trabalho é demonstrar a eficiência de modelos constitutivos formulados pelos fundamentos da Termodinâmica. Como exemplo da formulação abordada, é derivado um modelo constitutivo aplicado à análise de estruturas de concreto armado. As respostas numéricas obtidas com a aplicação do modelo são comparadas com uma série de respostas experimentais de vigas (biapoiadas e com diferentes taxas de armadura).Universidade Estadual De Maringá2009-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/37510.4025/actascitechnol.v31i1.375Acta Scientiarum.
