Evaluation of Ductile Damage Criteria in Hot Forming Processes
The process of ductile fracture which occurs due to the accumulation, growth and combination of defects or cracks of material is called ductile damage. Failure in materials can be predicted, using damage mechanics and damage criteria. On the other hand, most of the materials depended to the manufacturing process, are formed in warm or hot conditions so that; the temperature also affects on the ...
متن کاملassessment of the park- ang damage index for performance levels of rc moment resisting frames
چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...
15 صفحه اولBoron-containing Tool Coatings for Hot Forming
Analytical investigations of the test tools reveal in the most heavily stressed parts of the bolt signifi cantly different wear patterns for the tested variants also in microsections (Fig. 2). Data for a wear analysis evaluation regarding adhesion (positive values) and abrasion (negative values) have been obtained by using a 3-D coordinate measuring machine to compare the contour after stress t...
متن کاملSHEET ELECTROMAGNETIC FORMING USING CONVEX PUNCH INSTEAD OF CONVAVE DIE
High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...
متن کاملThe Optimization of Servo Press Method for Sheet Metal Forming
Recently in the field of sheet metal forming, servo press, which can control the speed and position of the tool using a servo motor, is attractive method. Development process of servo press method is accelerated as the capacity of servo motor become bigger. In the future, it’s expected as a great alternative plan to replace conventional press method in order to improve quality, increase product...
