[ 1 ] - The Effects of Inhomogeneous Mechanical Properties of the Ferrite Phase on Dual Phase Steel’s Behavior
The microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. Recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. In this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. I...
[ 2 ] - Finite Element Modeling and Experimental Study of the Spline Tube Forming
Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...
[ 3 ] - تحلیل ابعادی شکل دهی سازه نیم کُروی از آلیاژ تیتانیوم 4-6، به روش هیدرواستاتیک-سوپرپلاستیک
Experimental tests on superplastic forming of alloy Ti-6Al-4V with large dimensions can be quite difficult and expensive. In order to avoid the expense of manufacturing alloy sections, numerical modelling is used to simulate the alloy’s superplastic behaviour. However the results obtained from the numerical modelling need to be verified against experimental tests. In order to reduce the expense...
