1. Boundary element method formulation for reinforced porous material / Formulação do método dos elementos de contorno para materiais porosos reforçados
In this work a nonlinear formulation of the boundary element method (BEM) is proposed to deal with saturated and unsaturated poro-elasto-plastic 2D reinforced domains. To model reinforced porous domains a BEM/FEM (Finite Element Method) modified coupling technique is employed. The coupling is made by using the least square method to regularize the displaceme

2. ImplementaÃÃo e AplicaÃÃo do Modelo de Visco-dano para problemas geomecÃnicos
A great advance in development of constitutive models for better simulation of geomechanical materials behavior has been observed in the last decades. A continuous medium subjected to degradation of its mechanical properties has a differentiated constitutive answer; hence itâs required the adoption of models based in Mechanic of Continuous Damage formulated

3. ImplementaÃÃo de modelo de dano isotrÃpico aplicado a problemas acoplados hidro-geomecÃnicos
The macroscopic behaviour of a material can be described by constitutive models able to capture the structure observed along the application of several mechanical loading steps. The constitutive behaviour of a bedrock medium shows that for some stress levels hydromechanical models, based in poro-elasticity theories, represent in a satisfactory way the stress
