Abstract: The efficiency of fracture mechanics assessment of components using the finite-element method is discussed. The constraint modified J-integral concept describes the real behaviour of components well. The concept of damage mechanics offers new ways of assessing structures. The modified Gurson model can be applied successfully to predicting differences in the slopes of J-resistance curves of different specimen geometries.
Keywords: crack propagation; finite element method; FEM; fracture mechanics; fracture problems; Gurson model; J-resistance curves.
