Abstract: A recently developed equilibrium based curve/surface fitting method is extended to linear function with heteroscedastic data (variable variance). The concept of equilibrium weighted “forceâ€‌ and “momentâ€‌ is proposed ...

Abstract: Design curves, such as fatigue design SN curves, are usually constructed by analyzing test data, which often exhibit large scatter. There are several methods available to construct a design curve and some of these methods, ...
