EVALUACIÓN Y DETERMINACIÓN EXPERIMENTAL-­‐NUMÉRICA DEL ENDURECIMIENTO POR DEFORMACIÓN Y EL EFECTO BAUSCHINGER EN LAS PROPIEDADES MECÁNICAS DE UN ACERO INOXIDABLE

Abstract

Abstract. Material mechanical properties manipulation has recently been extremely important. Its relevance is based on improving the service life in the components. This is possible by applying strain hardening techniques and /or inducing beneficial residual stresses. In this work, is presented a numerical an experimental analysis concerning the characterization of a stainless steel AISI 316L. The importance of this kind of studies, is that a new methodology that can be use to improve the mechanical resistance of the material. By altering the mechanical properties of the material, it could be possible to delay the nucleation o interrupt the propagation of cracks. Also, it is presented by applying numerical tools, the manipulation of homogeneous and non homogeneous loading to vanish the possibility of failure. In the same sense, bending tests are proposed to provide tensile and compressive stress profile. Numeric evaluation is done using the Finite Element Method, experimental design is achieved in two parts. The first one is using the tensile, compression and flexion tests to manipulate the mechanical properties. As a second step considers the Crack Compleanse Method to obtain the residual stress.
