in this work dynamic recrystallization behavior of aisi 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 c -1200 c and strain rate range of 0.001 s-1 - 1 s-1. the obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. the flow stress and strain corresponding to the critical, pe...

Abstract Many advanced constitutive models which can capture the strain-softening and state-dependent dilatancy response of sand have been developed. These give good prediction single soil element behaviour under various loading conditions. But solution will be highly mesh-dependent when they are used in real boundary value problems due to strain-softening. They strain localization pattern bear...

We report structural, elastic, and electronic properties of selected, deformed, single-wall carbon nanotubes under uniaxial strain. We utilized a generalized gradient approximation potential of density functional theory and the linear combination of atomic orbital formalism. We discuss bond-lengths, tubule radii, and the band gaps as functions of tension and compression strain for carbon nanotu...

Because of its superior stretchability, graphene exhibits rich structural deformation behaviours and its strain engineering has proven useful in modifying its electronic and magnetic properties. Despite the strain-sensitivity of the Raman G and 2D modes, the optical characterization of the native strain in graphene on silica substrates has been hampered by excess charges interfering with both m...
