An extension of the Equivalent Material Concept applied to fracture of U-notched solids
Procedia Structural Integrity, 2020 Abstract The Equivalent Material Concept is a tool that allows the fracture behavior of notched components in elastoplastic materials to be analyzed by transforming them into fictitious linear elastic ones, defining a fictitious failure stress. The combination of a failure criterion with this approach offers a methodology for predicting the maximum ...
