The uniaxial tensile test has largely been performed to obtain the stress-strain relations and related mechanical properties of bulk specimens. However, there is an extra storage of defects associated with non-uniform plastic deformation in geometrically necessary dislocations, and ordinary macroscopic test alone, e.g. uniaxial tensile test, is not enough to capture the effects of such defects, e.g. plastic strain gradient. Besides, geometrically necessary dislocations are in th… WebJul 1, 2024 · For a variety of classical norms including induced ℓ p-norms, weakly unitarily invariant norms, and entrywise norms we give lower and upper bounds for ...
