Competing Indentation Deformation Mechanisms in Glass Using Different Strengthening Methods
Chemical strengthening via ion exchange, thermal tempering, and lamination are proven techniques for the strengthening of oxide glasses. For each of these techniques, the strengthening mechanism is conventionally ascribed to the linear superposition of the compressive stress (CS) profile on the glass surface. However, in this work, we use molecular dynamics simulations to reveal the underlying ...

15 صفحه اولDirect in situ observation of metallic glass deformation by real-time nano-scale indentation
A common understanding of plastic deformation of metallic glasses (MGs) at room temperature is that such deformation occurs via the formation of runaway shear bands that usually lead to catastrophic failure of MGs. Here we demonstrate that inhomogeneous plastic flow at nanoscale can evolve in a well-controlled manner without further developing of shear bands. It is suggested that the sample und...
متن کاملStudy of Mechanical Deformation in Bulk Metallic Glass through Instrumented Indentation
Instrumented sharp indentation experiments at the nanoand micro-length scales were carried out in an attempt to quantify the deformation characteristics of Vitreloy 1 bulk metallic glass. The experiments were accompanied by detailed three-dimensional finite element simulations of instrumented indentation to formulate an overall constitutive response. By matching the experimentally observed con...
متن کاملDeformation field heterogeneity in punch indentation.
Plastic heterogeneity in indentation is fundamental for understanding mechanics of hardness testing and impression-based deformation processing methods. The heterogeneous deformation underlying plane-strain indentation was investigated in plastic loading of copper by a flat punch. Deformation parameters were measured, in situ, by tracking the motion of asperities in high-speed optical imaging. ...
