COATED NANOPOROUS STRUCTURES SUBJECTED TO STRESS RELIEF ANNEALING

In this study, the mechanical improvement of the platinum coated nanoporous gold is investigated by performing molecular dynamics simulations. The tensile properties of the structure is enhanced by a stress relief annealing which prevents the high stress concentration observed between the coating and the core materials. The annealing process is performed at 500K for 100ps with a heating and coolin

Nonlinear mechanical behaviour and analysis of wood and fibre materials

The mechanical behaviour of wood was studied from a micro up to a macro level. Wood is a cellular material possessing a high degree of anisotropy. Like other cellular solids, it often exhibits a highly nonlinear stress–strain behaviour. In the present study the mechanical properties of the cellular structure of wood are characterized and modelled, the irregular cell shape, the anisotropic layered
