Paper Accepted for Publication in Applications in Engineering Science R. Bustamante, S. Montero, A. Ortiz-Bernardin, “A novel nonlinear constitutive model for rock: numerical assessment and benchmarking” ABSTRACT In this article, we assess and benchmark a novel nonlinear constitutive relation for modeling the behavior of rock, in which the linearized strain tensor is a function of

2016 – 2020 Principal Investigator: Roger Bustamante. Co-Investigator: Alejandro Ortiz-Bernardin. Project funded by CONICYT-FONDECYT (Grant Nº 1160030) 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
