Abstract Ductile damages often happen on metal structures under large deformations. In the current paper, ductile damage criteria are discussed from microscopic mechanism to fracture models. Abaqus FEA makes easy be applied for practical problems. Therefore, paper finally presents detailed implementation of in describe and degradation, simulating failure process with higher fidelity.

Although existing continuum models for the elasto-viscoplastic response of amorphous polymeric materials phenomenologically capture the large deformation response of these materials in a reasonably acceptable manner, they do not adequately account for the creep response of these materials at stress levels below those causing “macro-yield”, as well as the Bauschinger-type reverse yielding phenom...

in this paper, using numerical methods and test results, the behavior of reinforced concrete beams strengthened with fiber-reinforced polymers (frp) is investigated. in the numerical analysis, the concrete damaged plasticity model is used for considering the nonlinear behavior and strain softening of concrete. the abaqus finite element program is utilized for the analysis of 12 flexural beams s...

Abstract For welding temperature field, stress and strain field in fillet joints, using the double ellipsoid heat source, ABAQUS software platform is used to simulate analyze process of joints with four different application sequences. By setting up observation points, study analyzed distribution simulated for these cases. The results show that vertical weld direction, sequence has a large effe...
