Johnson-Cook constitutive equation is one of the most famous constitutive equations that have ever been developed to model the hot deformation flow curves of different materials. This equation is a predefined model in the traditional finite element codes to describe the material behavior in applications such as simulating the manufacturing processes. In this work, two different genetic algorith...
There is a requirement to find accurate parameters to accomplish precise dimensional accuracy, excellent surface integrity and maximum MRR. This work studies the influence of various cutting parameters on output parameters like Cutting force, Surface roughness, Flatness, and Material removal rate while face milling. A detailed finite element model was developed to simulate the face milling proc...
تخصیص منصفانه برای اولین بار طی مقاله ای توسط cook , kress بیان گردید.ایده ی اساسی بیان شده در این مقاله بر دو اصل استوار بود:اصل تغییر ناپذیری واصل حداقل پاراتو ورودی.سپس cook , zhu مقاله cook , kress را توسعه داده و در مقاله خود با عنوان تخصیص منابع و هزینه های مشترک به واحدهای تصمیم گیری (dmu) روشی برای چگونگی این تخصیص ارائه دادند. ولی ruiyue lin در مقاله خود با عنوان تخصیص هزینه و منابع ثا...
introduction: texture is one of the most important attribute in foods and is always issues for the manufacturing of fried products, because texture plays a crucial role in consumer acceptance and the perceived quality of foods. prediction of changes in texture during frying can be helpful in process control. structurally, this quality parameter in fried potato strip made from the formation of a...
In the Deep-drawing process, a blank is drawn into hollow element taking shape of die by operation punch. This process has numerous advantages and applications in automobile, aerospace, kitchenware, packaging industries. The primary purpose this study to design simulate deep drawing LS-Dyna PrePost(R) V4.6.17 using Johnson-Cook flow stress as material model. An appropriate judicious characteriz...
در اینجا ابتدا به روش هایی اکه cook $ zhu مطرح کرده اند پرداخته و با روشی جدید اشکالات این روش را رفع می کند
In this paper we will introduce well motivated definitions of computational complexity on type-2 objects. Similar to the model of Kawamura and Cook (and earlier models) our models will be both based on classical Turing machines and the notion of representations. The main differences to the model of Kawamura and Cook is that we give up type-2-polynomials and, additionally, use parameter based ty...
