- This paper provides a new bridge between continuum mechanics and discrete mechanics. The dynamics of nano-scale systems can be captured with an accuracy that is one order higher than previous models, whilst finite element discretisation is provided that is demonstrated to be no more complex than earlier, less accurate models. Subsequently this work achieves a notable step forward in computer modelling's balancing act between accuracy and efficiency. The paper is already attracting interest from adjacent theoretical (homogenisation theory, doi.org/10.1016/j.cma.2019.06.040) and more applied (piezoelectric energy harvesting devices, doi.org/10.1016/j.cma.2019.06.040) disciplines.
