Size effects and dislocation patterning in two-dimensional bending
, 2006 We perform atomistic Monte Carlo simulations of bending a Lennard-Jones single crystal in two dimensions. Dislocations nucleate only at the free surface as there are no sources in the interior of the sample.

Hydrostatic compression on polypropylene foam [PDF]
, 2014 Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to ...

Modelling of aluminium sheet forming at elevated temperatures [PDF]
, 2004 The formability of Al–Mg sheet can be improved considerably, by increasing the temperature. By heating the\ud sheet in areas with large shear strains, but cooling it on places where the risk of necking is high, the limiting drawing ratio\ud can be ...

The Genetic Basis of Mutation Rate Variation in Yeast. [PDF]
, 2018 Mutations are the root source of genetic variation and underlie the process of evolution. Although the rates at which mutations occur vary considerably between species, little is known about differences within species, or the genetic and molecular basis ...

Tensile-strength apparatus applies high strain-rate loading with minimum shock [PDF]
, 1966 Tensile-strength testing apparatus employs a capillary bundle through which a noncompressible fluid is extruded and a quick-release valve system. This apparatus applies the test loads at relatively constant very high strain rates with minimal shock and ...

Al-Li Alloys – The Analysis of Material Behaviour during Industrial Hot Forging [PDF]
, 2017 Al-Li alloys are a promising class of aerospace materials that combine light weight with high strength, comparable to those of steels. In the case of critical components, it is well known that providing the required reliability is impossible without ...

Characterisation of the high strain rate behaviour of tubular materials
EPJ Web of Conferences, 2018 Airbag gas generators used in the automotive industry are often fabricated from tubular materials. The present work deals with the development of split Hopkinson tensile bar (SHTB) tests for tubular samples. Tubular specimens were machined from the tubes.
