Computation of the plastic hardening curve based on a static tensile test

Mechanik, 2018
Numerical calculations, concerning, among other things, metal forming, based on the finite element method, require a description of the relationship between stress and strain in the entire load range. After crossing the yield point, the strain hardening is appearing. This phenomenon can be described by the plastic hardening curve.

PROGRESSIVE DAMAGE IN STITCHED COMPOSITES: STATIC TENSILE TESTS AND TENSION-TENSION FATIGUE

, 2009
The paper describes progressive damage in static tensile tests and tension-tension fatigue in structurally stitched carbon/epoxy NCF composites, in comparison with their non-stitched counterparts. Analogies between damage development in quasi-static tension and tension-tension fatigue are analyzed and links between the damage initiation thresholds in ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...
