Multifield-based modeling of material failure in high performance reinforced cementitious composites
(CIMNE, 2013)
Cementitious materials such as mortar or concrete are brittle and have an inherent weakness in resisting tensile stresses. The addition of discontinuous fibers to such matrices leads to a dramatic improvement in their ...
Computational modeling of high performance steel fiber reinforced concrete using a micromorphic approach
(Springer, 2013-01)
A finite element methodology for simulating the failure of high performance fiber reinforced concrete composites (HPFRC),with arbitrarily oriented short fibers, is presented. The composite material model is based on a ...
A micromorphic model for steel fiber reinforced concrete
(Elsevier, 2012-07)
A new formulation to model the mechanical behavior of high performance fiber reinforced cement composites with arbitrarily oriented short fibers is presented. The formulation can be considered as a two scale approach, in ...
A Review on Cementitious Self-Healing and the Potential of Phase-Field Methods for Modeling Crack-Closing and Fracture Recovery
(Molecular Diversity Preservation International, 2020-11)
Improving the durability and sustainability of concrete structures has been driving the enormous number of research papers on self-healing mechanisms that have been published in the past decades. The vast developments of ...
Programación o planeación de actividades o recursos en la agricultura. Una revisión de literatura
(Fondo Editorial EIA - Universidad EIA, 2018-11-26)
Con el propósito de detectar las herramientas y enfoques desarrollados en la programación de recursos o la planeación de actividades en la agricultura, el presente documento muestra la revisión sistemática de literatura ...
Metodología para la programación de la recolección manual de café en zonas con pendiente de inclinación superior a 20 %
(Manizales - Ingeniería y Arquitectura - Doctorado en Ingeniería - Industria y OrganizacionesDepartamento de Ingeniería IndustrialUniversidad Nacional de Colombia - Sede Manizales, 2019)
This doctorate thesis was carried out in the coffee sector of Colombia. Its main purpose was to design a scheduling methodology for manual coffee harvesting in farms with slope gradients above 20 %, in response to a lack ...
