Numerical and experimental studies of compression-tested copper, mortar contact method

Simulation of compression test of copper is made with the mortar contact method and assuming: axial symmetry, multiple point constraint of type plane, concentrate load and coulomb friction. Copper is simulated like isotropic material, elastic until it yields stress, and then like a hardening materia...

El cobre se simula como material isotrópico, elástico hasta fluencia, y luego como un material endurecible con plasticidad incremental. El comportamiento del cobre se calculó a partir de experimentos. Se realizaron diecisiete ensayos de compresión sin lubricación a muestras cilíndricas a temperatura ambiente. La relación Esfuerzo vs. Deformación  se calculó usando dos correcciones por fricción; La Corrección de Rowe y la Corrección Dieter. Se concluye que: la simulación realizada con el método de contacto con mortero y la Corrección Dieter es una buena alternativa para simular la prueba de compresión, siendo la diferencia entre la simulación y los experimentales inferior a 7,33%, la hipótesis de simetría axial no aleja la simulación de la realidad y nuevos análisis numérico permitirán el desarrollo de mejores correcciones por fricción.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
