An extension of the Equivalent Material Concept applied to fracture of U-notched solids [PDF]
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 ...

Fracture Load Predictions in Short Glass Fiber Reinforced Polyamide 6 U-Notched Specimens Combining the Equivalent Material Concept and the Theory of Critical Distances [PDF]
Journal of Testing and Evaluation, 2018 Abstract This article provides the prediction of fracture loads in single edge notched bending (SENB) specimens made of short glass fiber reinforced polyamide 6 (SGFR-PA6) and containing U-notches. The predictions are obtained through the combination of the equivalent material concept and the theory of critical distances (TCD).

Static assessment of plain/notched polylactide (PLA) 3D‐printed with different infill levels: Equivalent homogenised material concept and Theory of Critical Distances [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2018 AbstractA novel approach based on the equivalent homogenised material concept and the theory of critical distances is formulated to perform static assessment of plain/notched objects of polylactide (PLA) when this polymer is additively manufactured with different infill levels.

Prediction of fracture loads in PMMA specimens using the Equivalent Material Concept and the Theory of Critical Distances combined criterion [PDF]
, 2017 This paper provides a methodology for the prediction of fracture loads in notched materials that combines the Equivalent Material Concept with the Theory of Critical Distances. The latter has a linear-elastic nature, and requires material (critical distance) calibration in those cases where the non-linear material behaviour is significant.

Equivalent Morphology Concept in Composite Materials Using Machine Learning and Genetic Algorithm Coupling [PDF]
Journal of Composites ScienceThe objective of this study is to investigate the synergistic integration of machine learning and evolutionary algorithms for the discovery of equivalent morphologies exhibiting analogous behavior within the domain of composite materials. To pursue this objective, two comprehensive databases are meticulously constructed.

Equivalent stress concept for limit state analysis [PDF]
, 2022 In this book, criteria for isotropic materials based on the equivalent stress concept are discussed. These criteria are widely applied in the limit state analysis. For general use, they are formulated in the invariants of the stress tensor.
