Numerical implementation of a micromechanics-based viscoelastic model for geomaterials with isotropically distributed micro-fractures
(2019) [Artículo de periódico]The constitutive behavior of geomaterials is generally affected by the presence at different scales of discontinuity surfaces with different sizes and orientations. According to their mechanical behavior, such discontinuities ... -
A numerical investigation of inertia flows of Bingham-Papanastasiou fluids by an extra stress-pressure-velocity galerkin least-squares method
(2010) [Artículo de periódico]This article is concerned with finite element approximations for yield stress fluid flows through a sudden planar expansion. The mechanical model is composed by mass and momentum balance equations, coupled with the Bingham ... -
A numerical investigation of the resin flow front tracking applied to the RTM process
