Ítem Thermodynamic theory for damage evolution in solids(2014-05-01) GOMEZ, JUAN DAVID; GOMEZ, JUAN DAVID; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaÍtem Experimental Analysis of the Lateral Resistance of a Shear Critical Reinforced Concrete Frame(Sociedade Portuguesa de Engenharia Sismica (SPES), 2012-09-24) Acevedo A.B.; Bonett, R.L.; Carmona, O.; Acevedo A.B.; Bonett, R.L.; Carmona, O.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaFlexural behaviour of reinforced concrete (RC) frames is a well-studied topic that has been evaluated both analytical and experimentally. Contrarily, shear failure of RC frames have been studied in a lesser amountÍtem Spectral element method for dispersion relations of phononic crystals(2012-07-13) Guarin, Nicolas; Gomez, J.; Guarin, Nicolas; Gomez, J.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaThe mechanical response of heterogeneous solids below a given length scale starts to be controlled by the existing microstructure. In the case of periodic heterogeneities the materials are known as phononic crystalsÍtem Thermodynamics Theory for Damage Evolution in Solids(Springer New York, 2015-01-01) Basaran, Cemal; Nie, Shihua; Gomez, J.; Gunel, Eray; Shidong Li; Minghui Lin; Hong Tang; Chengyong Yan; Wei Yao; Hua Ye; Basaran, Cemal; Nie, Shihua; Gomez, J.; Gunel, Eray; Shidong Li; Minghui Lin; Hong Tang; Chengyong Yan; Wei Yao; Hua Ye; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaIn this chapter the thermodynamic theory behind damage mechanics is presented. The presented damage evolution model is purely physical, rather than empirical. Entropy production rate is used as a damage metric.Ítem Método basado en desplazamientos para el diseño y evaluación de la vulnerabilidad sísmica de puentes de concreto reforzado(Fondo Editorial Universidad EAFIT, 2011-05-31) Alejandro Ospina; Hector Urrego; Botero, Juan Carlos; Alejandro Ospina; Hector Urrego; Botero, Juan Carlos; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaSe propone una metodología que describe un procedimiento para analizar la capacidad de un elemento estructural, basado en las propiedades resultantes su diseño inicial o de un predimensionamiento con buen criterio, deduciendo de su equilibrio internoÍtem Numerical Modeling of Wave Reflection in a Dispersive Micropolar Half-Space(2012-07-13) Velez, Francisco Javier; Gomez, J.; Guarin, Nicolas; Velez, Francisco Javier; Gomez, J.; Guarin, Nicolas; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaIn this work wave propagation is studied considering the role played by the microstructural entities described by a non-classical solid, like the Cosserat or micropolar medium [1].Ítem Numerical analysis of the modal coupling at low frequencies in the Colombian Andine Bandola(2012-07-13) Gomez, Sara R.; Guarin, Nicolas; Gomez, Sara R.; Guarin, Nicolas; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica AplicadaMusical acoustics have emerged as a branch that studies the sound produced for musical purposes. The specific subject of acoustics of strings instruments like guitar and violinÍtem Epistemic uncertainty quantification for 1D ground response analysis using fully nonlinear models(CRC Press, 2019-10-22) V. Alves Fernandes; Montoya, S.; F. López-Caballero; E. Foerster; M. Jacquet; D. Vandeputte; V. Alves Fernandes; Montoya, S.; F. López-Caballero; E. Foerster; M. Jacquet; D. Vandeputte; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
