The intergranular cracking in the Mg-Gd-Y alloy was investigated by an situ tension test combined with electron backscattered diffraction (EBSD) measurement and digital image correlation (DIC). During test, crack found at triangle point of grain boundary area profuse slip traces. DIC results show that inhomogeneous strain distribution can be area, leads to serious deformation incompatibility th...

The modifying effects of flavonoids diosmin and hesperidin during the initiation and post-initiation phases of oesophageal carcinogenesis initiated with N-methyl-N-amylnitrosamine (MNAN) were investigated in male Wistar rats. At 7 weeks of age, all animals except those treated each test chemical alone and control groups were given weekly intraperitoneal injections of MNAN (12.5 mg/kg body weigh...

Cold forming has required considerably superior hard coating on a die to manufacture net-shaped products. Especially, under poor lubrication conditions or dry condition, the is indispensable for success of manufacturing. Accordingly, prevent adhesion, reduce friction, and control wear. Recently, it been also necessary improve life product qualities severe tribological conditions. However, compr...

A thermodynamically consistent damage model is proposed for the simulation of progressive delamination in composite materials under variable-mode ratio. The model is formulated in the context of Damage Mechanics. A novel constitutive equation is developed to model the initiation and propagation of delamination. A delamination initiation criterion is proposed to assure that the formulation can a...

This paper evaluates a smoking prevention intervention aimed at vocational school students, consisting of an existing Dutch in-school program (three lessons each lasting 50 min) and a computer-based tailored out-of-school program (three tailored letters with smoking prevention messages mailed to students' homes). Nineteen schools that already participated in the in-school program were randomly ...
