Effect of Strain Induced Martensite on the Deep Drawing Behavior of 304L Steel: Simulation and Experiment
Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...
متن کاملOptimization of parameters of Anti lock Braking System for use in deep drawing
A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
Application of Abductive Network and FEM to Predict the Optimal Blank Contour of Elliptic Cylindrical Cup in Deep Drawing
In this paper, the finite element method is employed in conjunction with the abductive network to predict the optimum blank contour of elliptic cylindrical cup with ear-less in deep drawing. The earring behavior of the formed cup is caused primarily by planar anisotropy in the sheet. Different cup heights combined with various aspect ratios of the elliptic cylindrical cup are taken into account...
