Communication avec acte(CIMNE, 2017)In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory. The resulting approach is implemented ...

Scalar-based strain gradient plasticity theory to model size-dependent kinematic hardening effects Article dans une revue avec comité de lecture(Springer Verlag, 2021)A common belief in phenomenological strain gradient plasticity modeling is that including the gradient of scalar variables in the constitutive setting leads to size-dependent isotropic hardening, whereas the gradient of ...
-
Article dans une revue avec comité de lecture(Elsevier, 2021)A novel single shear specimen (SSS) together with a correction coefficient method is used to study the deformation behavior of a 304 stainless steel under shear loadings. Shear stress-shear strain relations over a wide ...
-
Article dans une revue avec comité de lecture(2021)Buckling and wrinkling of thin structures often lead to very complex response curves that are hard to follow by standard path-following techniques, especially for very thin membranes in a slack or nearly slack state. Many ...

Article dans une revue avec comité de lecture(Elsevier BV, 2021)This paper presents the results of high temperature strain-range controlled low cycle fatigue tests of a laser powder bead fused AlSi10Mg alloy. Following stress relief (2hrs at 300 ℃), two cyclic loading waveforms (standard ...

Article dans une revue avec comité de lecture(MDPI AG, 2021)The present paper aims at providing a comprehensive investigation of the abilities and limitations of strain gradient crystal plasticity (SGCP) theories in capturing different kinds of localization modes in single crystals. ...

Article dans une revue avec comité de lecture(Elsevier BV, 2021)We present in this investigation an advanced phenomenological approach combining the computational efficiency of classical phenomenological plasticity models and the accuracy and high resolution of multiscale crystal ...
