Abstract: In sequential of multistep forming operations, the material which has already undergone permanent deformation is expected to behave differently in each stage of deformation than the as-received ...

Abstract: In the present investigation, we have studied the influence of sheet thickness on the limiting strain, i.e., forming limit, of a mild steel by punch stretching experiments. Our results show ...

Abstract: An analytical diffusion model for flood routing which can take into account backwater effect and lateral flows has been developed. The model is applied to route the floods in a hypothetical rectangular channel with different ...

Abstract: The development of a one-dimensional finite strain elasto-plastic shell model appropriate for use in modelling straight drawbeads is outlined. Numerical results obtained using a finite element ...

Abstract: Yttria and alumina have been used with particular success, either singly or in combination, as densification aids for hot pressing and sintering of silicon nitride. To obtain desirable mechanical, ...

Abstract: This paper presents a set of experimental results concerning the evolution of yield loci for anisotropic materials in the course of finite shear deformation history. Thin walled tubes of SAE ...

Abstract: Many metal forming operations, such as rolling and tube drawing, are known to induce orthotropic anisotropy. The change of axes of orthotropy with subsequent deformation has been studied in ...

Abstract: In an effort to reduce the harmful effects of greenhouse gas emissions, ammonia is being pursued as a fuel for power generation as it is a carbon-free energy source. However, the use of ammonia-air mixtures in premixed ...

Abstract: An expression for the entrainment in a channel with rippled bed has been developed considering the entrainment mechanism. The flow structure behind the ripple has been modeled on an eye‐shaped line vortex. Afterwards, the ...
