On the use of implicit constitutive relations to model the behaviour of elastic and inelastic deformations in continua: Applications to the mathematical modelling of rock

Principal Investigator: Roger Bustamante. Co-Investigator: Alejandro Ortiz-Bernardin. Project funded by Fondecyt-Conicyt Geomaterials such as rock and soil can show a plethora of nonlinear phenomena regarding their mechanical behaviour, such as: hysteresis (i.e., dependency of the mechanical properties in the load history), nonlinear relations between stresses and strains (even in the case of considering small strains),…

Study of Some New Constitutive Laws for Elastic Bodies

Principal Investigator: Roger Bustamante. Co-Investigator: Alejandro Ortiz-Bernardin. In the classical theory of continuum mechanics there are two concepts which are considered particularly important, namely stresses and strains. Even though, from an intuitive point of view, we would say that strains are ‘caused’ due to the presence of stresses in a body, when proposing constitutive laws…
