Averaging Molecular Dynamics simulations to study the slow-strain rate behavior of metals
Sarthok Kumar Baruah, Sabyasachi Chatterjee, Amit Acharya +1
The application of molecular dynamics (MD) simulations to quasistatic loading is severely limited by the large separation between atomic vibration timescales and experimentally rel…
Coupled Dislocations and Fracture dynamics at finite deformation: model derivation, and physical questions
Amit Acharya
A continuum mechanical model of coupled dislocation based plasticity and fracture at finite deformation is proposed. Motivating questions and target applications of the model are s…
Mid-surface scaling invariance of some bending strain measures
Amit Acharya
The mid-surface scaling invariance of bending strain measures proposed in [Acharya (2000)] is discussed in light of the work of [arXiv:2010.14308].
A Hidden Convexity in Continuum Mechanics, with application to classical, continuous-time, rate-(in)dependent plasticity
Amit Acharya
A methodology for defining variational principles for a class of PDE models from continuum mechanics is demonstrated, and some of its features explored. The scheme is applied to qu…
