چکیده انگلیسی
This paper presents the experimental assessment of two simplified models, formulated in a companion paper by the authors, that estimate the elastic–plastic behavior at the notch-root surface of particulate metal matrix composites (PMMCs). The validity of each model is assessed by measuring the notch root strains on circumferentially notched PMMC bars when subjected to a variety of bi-axial cyclic loading paths. The notch root strains are measured using a 3D image correlation system that uses photogrammetric principles and image processing in assessing surface strain fields. Both models are found to be in good agreement with the experimental results in terms of the shape and orientation of the elastic–plastic local shear and axial strains.
