Application of the Theory of the Critical Distances based methodology for the analysis of Environmentally Assisted Cracking processes in biomaterials
González, Pablo; Cicero, Sergio; Peron, Mirco; Arroyo, Borja; Alvarez, Jose Alberto; Berto, Filippo (Peer reviewed; Journal article, 2020)The complex interaction between physiological stresses and corrosive human fluids can lead to the premature failure of metallic biomaterials due to the development of Environmental Assisted Cracking (EAC) processes. In ... -
Estimation of Fracture Loads in AL7075-T651 Notched Specimens Using the Equivalent Material Concept Combined with the Strain Energy Density Criterion and with the Theory of Critical Distances
Fuentes, Juan Diego; Cicero, Sergio; Berto, Filippo; Torabi, Ali reza; Madrazo, Virginia; Azizi, Payman (Journal article; Peer reviewed, 2018)The main goal of this paper is the application of the Strain Energy Density (SED) criterion and the Theory of Critical Distances (TCD), both of them in combination with the Equivalent Material Concept (EMC), to predict the ... -
Extension of the equivalent material concept to compressive loading: Combination with LEFM criteria for fracture prediction of keyhole notched polymeric samples
Torabi, Ali Reza; Hamidi, Kazem; Shahbazian, Behnam; Cicero, Sergio; Berto, Filippo (Peer reviewed; Journal article, 2021)This work analyzes, both theoretically and experimentally, the fracture process of square specimens weakened by keyhole notches and subjected to compressive stresses. Two materials are covered: general-purpose polystyrene ...
