Assessment of crack growth development in main pipeline on the basis of elastoplastic model
A method for predicting the growth of surface cracks in the wall of the main pipeline under action of operational loads is proposed. The elastoplastic model of surface crack growth under biaxial loading is described on the example of steel 20. ANSYS developed an algorithm for modeling crack grow...

| description | A method for predicting the growth of surface cracks in the
wall of the main pipeline under action of operational loads is
proposed. The elastoplastic model of surface crack growth under
biaxial loading is described on the example of steel 20. ANSYS
developed an algorithm for modeling crack growth taking into
account residual stresses. The forms and sizes of crack opening
under varying loading cycles of the pipeline are determined. The
dependence of the crack growth rate under varying loads on the
stress state in front of the crack tip is established. The influence
of overload cycles on crack growth is investigated. The technique
of crack development prediction based on in-line diagnostics and
pipeline loading monitoring is described. |
