Scaling Under Dynamic Uncertainty Using Laws of Growth

This paper gives an overview of methods used to describe uncertainty in size range development. Laws of growth, scenario laws of growth and probabilistic laws of growth are extended to allow the calculation of dynamic, size-dependent product behaviour. Dynamic product behaviour can depend on time or load cycles, such as corrosion and wear. Effects such as these can be size-dependent, an issue that is also considered in this paper. The extended methods are explained using a pushrod as an example product.
