Timber Creep of Historic Urban Quay Walls: The influence of timber creep on the assessment of inner-city quay walls

Amsterdam and many other cities consist of a network of old quay walls, which sometimes have been constructed over a century ago. A large uncertainty exists concerning the current safety of these quay walls and their remaining service lifetime. In the current framework for the assessment of old urban quay walls, the influence of timber creep in...

Finite element modelling of creep cavity filling by solute diffusion

In recently discovered self healing creep steels, open-volume creep cavities are filled by the precipitation of supersaturated solute. These creep cavities form on the grain boundaries oriented perpendicular to the applied stress. The presence of a free surface triggers a flux of solute from the matrix, over the grain boundaries towards the...

Modelling and simulation of bone implant healing

In this report a model for the ingrowth of a prosthesis in a bone will be formulated and simulated. First an overview is given of all the biological processes that are part of this healing process and what external factors can influence this process. Then a first mathematical model is presented in which the mechanical stimuli (one of the...
