Kowalewski Z.L., Dubey V.P., Kopeć M., ASSESSMENT OF INITIAL AND SUBSEQUENT YIELD SURFACES OF TI-CU BIMETALLIC STRUCTURE AFTER PRE-DEFORMATION INTRODUCED BY COMPLEX LOADING,
XL ZJAZD DELEGATÓW PTMTS, XII KONFERENCJA Nowe Kierunki Rozwoju Mechaniki IX SYMPOZJON, 2024-03-13/03-16, Łężyce 48 (PL), pp.1-2, 2024![](/images/nota.jpg) Streszczenie: Investigating of the material properties and physical mechanisms responsible for plastic deformation caused by complex loading is crucial for bimetallic structures. These materials are a type of functionally graded multi-material structures designed to combine diverse material properties within the same framework while optimizing manufacturing costs. In the present work, the initial yield surface and its subsequent evolution were determined for a Ti-Cu bimetal based on the definition of yield stress for 0.01% plastic offset strain. The subsequent yield surfaces were determined after introducing monotonic axial tension and axial tension-cyclic torsion pre-deformation up to 1% permanent axial strain. It was found, that the determined initial yield surface was close to the Huber-Mises locus. Furthermore, subsequent yield surfaces were determined to assess a hardening/softening effect in the loading direction applied. Interestingly, only the monotonic tension caused a significant enhancement of the tensile yield strength as the monotonic tension associated with cyclic torsion caused its reduction. On the other hand, the sizes of subsequent yield surfaces reflecting pre-deformation were reduced in the axial compression direction. Afiliacje autorów:
