Abstract : In predicting the behaviour of material systems, agreement between prediction and observation is frequently unsatisfactory even when an accurate theory is available, because values for some of the material constants are incorrectly assumed or not known. In these circumstances better predictions can be made by allowing the constants to take best-fit values between plausible limits. The method is discussed and experimental work described to confirm the accuracy of this type of prediction. (Author)
