About the event

Microlattices are known to have improved mechanical properties compared to their equivalent solid parts and have sparked many interests in the research communities. For the modelling of such materials with lattice microstructures, various techniques can be used. An emergent theory, the gradient elasticity continuum, can be applied to this microstructure efficiently and effectively by containing higher-order spatial derivatives. The formulation of the continuum requires techniques to retain the geometric and mechanical properties of the lattices and to derive continua which are simple and easy to use in numerical methods such as finite element modelling. The research also works on three different geometries: square, trapezium and diamond lattices. Further investigations on the implementability of the new continua are presented with examples.
