Hi all,
I am modelling a steel Double edge notched tensile (dent) specimen in abaqus/implicit. I used for the model isotropic hardening, the material properties are acquired from standard uni-axial tensile experiment, quad elements with reduced integration are used and a very refined mesh near the notches in the ligament area. I correlated the simulation results with the experimental data however I didn't obtain a good correlation especially the plastic part as shown in attachment. I tried to refine the mesh and change the element type but without success, any suggestion to improve the correlation would be appreciated.
Thank you in advance.
