Evaluation of the Strain Energy Density Value without the Construction of the Control Volume in the Preprocessing Phase of the Finite Element Analysis
Foti, Pietro; Berto, Filippo (Journal article; Peer reviewed, 2019)This work investigates the error in the evaluation of the Strain Energy Density value when it is evaluated without the construction of the control volume in the pre-processing phase of the finite element analysis. Several ... -
Fatigue Assessment of Welded Components through Local Approaches
Foti, Pietro (Doctoral theses at NTNU;2021:309, Doctoral thesis, 2021)Fatigue is a phenomenon having local nature; it is obvious that an accurate fatigue assessment of a component must take into account the local parameters as close as possible to the reality. Fatigue in welded components ... -
Fatigue assessment of welded joints by means of the strain energy density method: Numerical predictions and comparison with eurocode 3
Foti, Pietro; Filippi, S; Berto, Filippo (Journal article; Peer reviewed, 2019)The main aim of the present work is to investigate the effects of different parameters on the fatigue strength of four different welded details through an energetic approach based on the Strain Energy Density failure ... -
Fracture assessment of U-notched PMMA under mixed mode I/II loading conditions by means of local approaches.
Foti, Pietro; Razavi, Seyed Mohammad Javad; Berto, Filippo (Peer reviewed; Journal article, 2021)The paper investigates the fracture behaviour of U-notched specimens made of polymethylmethacrylate at room temperature under mixed mode loading conditions. The specimens are flat and double notched. The notches bisectors ... -
Francis-99: Evaluation of the strain energy density value for welded joints typical of turbine runner blades
Foti, Pietro; Berto, Filippo (Journal article; Peer reviewed, 2019)The main aim of this work is to investigate the fatigue behaviour of welded joints through an energetic approach based on the Strain Energy Density failure criteria. The geometries, taken from the literature, are typical ... -
On the application of the volume free strain energy density method to blunt V-notches under mixed mode condition
Foti, Pietro; Razavi, Seyed Mohammad Javad; Ayatollahi, M; Marsavina, L; Berto, Filippo (Peer reviewed; Journal article, 2020)This work investigates the possibility to apply the strain energy density method, as regards blunt V-notches under mixed loading condition, through finite element models with a free mesh pattern. It is worth underlining ... -
Rapid Strain Energy Density evaluation for V-notches under mode I loading conditions
Foti, Pietro; Berto, Filippo; Ayatollahi, Majid Reza (Peer reviewed; Journal article, 2020)This work investigates the possibility to evaluate the Strain Energy Density value with a free mesh model suggesting the use of a correcting formula a posteriori. Several numerical analyses were carried out to prove the ... -
Strain Energy Density evaluation with free coarse mesh model
Foti, Pietro; Berto, Filippo (Journal article, 2019)This work investigates the error in estimating the strain energy density value through a free coarse mesh model in a finite element analysis. Several numerical simulations were carried out to acquire this value both according ... -
Volume Free Strain Energy Density Method for Applications to Blunt V-Notches
Foti, Pietro; Razavi, Seyed Mohammad Javad; Marsavina, Liviu; Berto, Filippo (Peer reviewed; Journal article, 2020)This work investigates the application of the strain energy density method to rounded V-notches under mode I loading conditions and to components without stress concentrators through finite element models that do not involve ...
