The yield criterion, or so-called function, plays an important role in the study of plastic working a sheet because it governs deformation properties during plastic-forming process. In this paper, we propose novel anisotropic function useful for describing behavior various sheets. proposed includes version second stress invariant J2 and third J3. can explain sheets by introducing parameters α β...

To fully exploit the predictive accuracy of advanced anisotropic yield functions, a large number classical mechanical tests is required for calibration purposes. The Finite Element Model Updating (FEMU) technique enables to simultaneously extract multiple parameters when fed with heterogeneous strain fields obtained from single information-rich experiment. This inverse approach has potential mi...

Increased water demands and drought have resulted in the need to provide data guide deficit management decisions irrigated maize ( Zea mays L.) for grain production. The objective of this study was develop relationships between yield use (ETc, crop evapotranspiration) under low high nitrogen (N) input systems on a soil type (silt loam) common production arid Northwest U.S. treatments consisted ...

Received (Day Month Year) Revised (Day Month Year) Communicated by (xxxxxxxxxx) The scope of renable functions in wavelet theory is focused to localized functions. In our paper we like to widen that scope, in particular we show that all polynomial functions are renable. This may yield an interesting notion of convolution of polynomials.
