Strain-rate dependence for Ni/Al hybrid foams [PDF]
EPJ Web of Conferences, 2015 Shock absorption often needs stiff but lightweight materials that exhibit a large kinetic energy absorption capability. Open-cell metal foams are artificial structures, which due to their plateau stress, including a strong hysteresis, can in principle ...

Strain rate dependency of dislocation plasticity [PDF]
Nature Communications, 2021 AbstractDislocation glide is a general deformation mode, governing the strength of metals. Via discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain rate and dislocation density dependence of the strength of bulk copper and aluminum single crystals.

Evaluation of impact ductile fracture behaviour of low carbon austenitic stainless steel SUS304L using damage mechanics model [PDF]
EPJ Web of Conferences, 2021 To clarify the applicability of the Gurson-Tvergaard-Needleman (GTN) model for impact ductile fracture behaviour, SHB test was reproduced by finite element analysis (FEA).

Strain rate dependence of SM490B at room temperature and application to Cowper-Symonds constitutive models [PDF]
EPJ Web of Conferences, 2021 Steel is widely used as a constituent material for various structures such as automobiles and ships. To perform high precision analysis including high strain rate behavior, an understanding for the strain rate dependence of material strength becomes very

Programming Strain Rate Dependency into Mechanical Metamaterials [PDF]
EPJ Web of Conferences, 2021 This work presents an approach to introduce significant strain rate sensitivity into metallic metamaterials that are manufactured via additive manufacturing, where the base material employed will typically have a weak strain rate sensitivity. Here, we employ friction between the rough surfaces as the strain-rate dependent mechanism, whose magnitude is ...

Journal of Glaciology, 2022 The response of ice to applied stress on ice-sheet flow timescales is commonly described by a non-linear incompressible viscous fluid, for which the deviatoric stress has a quadratic relation in the strain rate with two response coefficient functions ...

Strain Rate Dependence of Twinning Behavior in AZ31 Mg Alloys
Metals, 2023 This study investigates the impact of strain rate on the twinning process (i.e., twin nucleation, twin propagation, and twin growth) and associated mechanical behavior during compression along the normal direction (ND) and transverse direction (TD) of a ...
