Criterios de predicción de inestabilidades plásticas en procesos de conformado en caliente. (Parte I: Revisión teórica)

Abstract: ResumenLos procesos de conformado de materiales inducen frecuentemente altos grados de deformación, a grandes velocidades de deformación, e imponen modos de solicitación multiaxiales y muy complejos. Dichos procesos quedan esencialmente limitados por la aparición y desarrollo de inestabilidades plásticas. Éstas pueden ser la causa directa de la propagación rápida de una fisura, que puede dar lugar a una rotura final. La complejidad de los modos de deformación y la intervención simultanea de varios parámetros h… Show more

“…Guechichi and Castex (2006), predicted the fatigue limit for cyclical loading of surface treated materials, including nitriding. In this sense, it is important a comparison between theoretical and experimental data, emphasizing in the importance of computations in materials science, an important tool for an easier interpretation and identification of small details of the materials (Al Omar and Prado, 2010).…”
