The degree of plastic deformation that a metal can sustain before fracturing can largely be characterised in a tensile test. However, some metals (not many) are brittle, or can fracture prematurely during tensile tests.","pdf":{"publicURL":"/static/603744674249951d54c65ab552f92df1/premature-fracture.pdf"}}}},{"node":{"frontmatter":{"title":"Tension and Compression Asymmetry and the Bauschinger Effect","date":"2021-07-21T08:30:24.798Z","description":"There is quite frequent reference in the literature to “tension/compression asymmetry”, meaning a difference between the inherent (plasticity) responses of a material when subjected to (uniaxial) compression or tension. This is largely a myth. Find out why in this article.","pdf":{"publicURL":"/static/091f1684f7e4ffd755f28c84a22a2316/asymmetry.pdf"}}}},{"node":{"frontmatter":{"title":"Necking Behaviour during Uniaxial Tensile Testing","date":"2021-04-21T13:46:44.816Z","description":"Necking is observed in most tensile tests on metals, but detailed interpretation of stress-strain curves in the post-necking regime is complex, and frequently misunderstood.","pdf":{"publicURL":"/static/164de9595dff9384661276421d832e6e/plastometrex_necking_and_fracture.pdf"}}}},{"node":{"frontmatter":{"title":"Size and Shape Effects in Plasticity Testing","date":"2020-12-16T14:45:02.273Z","description":"We explain why indentation on the nanoscale can never be used to reliably extract bulk mechanical properties from indentation tests, and we review the potential origins of indentation size effects and pop-in phenomena.\n","pdf":{"publicURL":"/static/9b089f5431c95608fb9f8141939882ef/plastometrex_size_effects.pdf"}}}},{"node":{"frontmatter":{"title":"The Hard Truth about Hardness Numbers","date":"2020-07-21T13:39:51.910Z","description":"Here is our view on why hardness numbers are as good as meaningless, and how they could be misleading your decision making processes around material safety and component integrity.","pdf":{"publicURL":"/static/5c3d457d1f08b0d5f08575e83c2d110f/plastometrex_hardness_testing.pdf"}}}}]}}}
