Abstract: [cze] [eng]
The concept of J-R curves is well established in structure assessment.However, the shape of J-R curves is influenced by constraint effectssignificantly. Such phenomena can be modelled using micromechanicalmodels of plasticity.The paper presents simulation of J-R curves usingthe complete Gurson model of plasticity, which was implemented into thefinite element system WARP3D.
