Competing indentation deformation mechanisms in glass using different strengthening methods

open access: yesFrontiers in Materials, 2016
Chemical strengthening via ion exchange, thermal tempering, and lamination are proven techniques for strengthening of oxide glasses. For each of these techniques, the strengthening mechanism is conventionally ascribed to the linear superposition of the ...

A Novel approach to the description of constitutive relations

open access: yesFrontiers in Materials, 2016
Recent advances in the development of implicit constitutive relations to describe the response of both solids and fluids have greatly increased the repertoire of the modeler in his ability to describe natural phenomena more faithfully than hitherto ...

Monitoring of self-healing cementitious materials through contactless ultrasound [PDF]

open access: yesMATEC Web of Conferences, 2023
Self-healing cementitious composites provide an alternative to labour-intensive and costly manual repairs. While a cementitious blend possesses an inherent ability to repair its own damage through autogenous healing, an enhancement of the self-healing ...
