... analysis (FEA) usually uses origin-oriented spring models with nonlinear characteristics, such as the R-O model, which makes it difficult to accurately represent history loops due to cyclic loading. Hence, the authors have studied a detailed manner to propose an elastoplastic analysis method for piping...

... experimental data and data derived with simplified empirical elastoplastic tools. This paper highlights the difficulties of performing such elastoplastic analysis and compares the obtained results with those obtained using more classical tools for elastoplastic analysis (Glinka and Seeger–Heuler). It was found...
