Validating bond-based peridynamic model using displacement potential approach
Autor: Jared Rivera, Yuzhe Cao, Longwen Tang, Mathieu Bauchy
Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science. 237:2877-2886
Although peridynamics is widely used to investigate mechanical responses in materials, the ability of peridynamics to capture the main features of realistic stress states remains unknown. Here, we present a procedure that combines analytic investigat

The brittle-to-ductile transition in aluminosilicate glasses is driven by topological and dynamical heterogeneity
Autor: Longwen Tang, Morten M. Smedskjaer, Mathieu Bauchy
Publikováno v: Tang, L, Smedskjær, M M & Bauchy, M 2023, ' The brittle-to-ductile transition in aluminosilicate glasses is driven by topological and dynamical heterogeneity ', Acta Materialia, vol. 247, 118740 . https://doi.org/10.1016/j.actamat.2023.118740
Amorphous materials can exhibit varying degrees of nanoscale ductility depending on their atomic structure. Despite its critical importance for applications, the physical origin that controls ductility remains largely unknown. Here, by using molecula

Atomic structure dictates the performance of all materials systems; the characteristic of disordered materials is the significance of spatial and temporal fluctuations on composition-structure-property-performance relationships. Glass has a disordere

Flaw-free amorphous alumina (a-Al2O3) samples have recently been found to exhibit excellent nanoductility at room temperature and under high strain rate. A better understanding of the underlying ductile deformation mechanism could help to facilitate

The energy landscape governs ductility in disordered materials
Autor: Gang Ma, Mathieu Bauchy, Normand Mousseau, Tao Du, Han Liu, Wei Zhou, Longwen Tang
Publikováno v: Materials Horizons. 8:1242-1252
Based on their structure, non-crystalline phases can fail in a brittle or ductile fashion. However, the nature of the link between structure and propensity for ductility in disordered materials has remained elusive. Here, based on molecular dynamics
