Determining large-strain metal plasticity parameters using in-situ measurements of plastic flow past a wedge
Harshit Chawla, Shwetabh Yadav, Hrayer Aprahamian +1
We present a novel approach to determine the constitutive properties of metals under large plastic strains and strain rates that otherwise are difficult to access using conventiona…
Nucleation properties of isolated shear bands
Shwetabh Yadav, Dinakar Sagapuram
Shear banding, or localization of intense strains along narrow bands, is a plastic instability in solids with important implications for material failure in a wide range of materia…
Shear bands in materials processing: Understanding the mechanics of flow localization from Zener's time to the present
Koushik Viswanathan, Shwetabh Yadav, Dinakar Sagapuram
Shear banding is a material instability in large strain plastic deformation of solids, where otherwise homogeneous flow becomes localized in narrow micrometer-scale bands. Shear ba…
Surface plastic flow in polishing of rough surfaces
Ashif S. Iquebal, Dinakar Sagapuram, Satish Bukkapatnam
We report electron microscopy observations of the surface plastic flow in polishing of rough metal surfaces with a controlled spherical asperity structure. We show that asperity--a…
