investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Numerical Investigations on the Effect of Pulsating Pressure on Improvement of Formability in Hydroforming of Bent Tube by FEM
In this paper, hydroforming process of bent tubes in T-shaped die is studied for pulsating and linear pressure paths by the finite element method. Forming Limit Diagrams (FLDs) and thickness distribution curves are used to investigate the effect of pulsating pressure on hydroforming process. In addition, the obtained numerical results are compared with experimental results of hydroforming of st...
متن کاملForming of Multi layer Sheet Metal by Drawing Process: an Analysis and FEM Simulation
In this paper, the drawing process of multi-layer sheet metal through wedge shaped die has been analyzed using stream function and upper bound method. Typically a sandwich sheet contains three layers of metal, where the outer layers are of the same thickness and material and different from those of the inner layer. In this study, a new deformation model has been introduced in which inlet and ou...
متن کاملHigh Performance FEM Simulation
Processor technology is still dramatically advancing and promises further enormous improvements in processing data for the next decade. On the other hand, much lower advances in moving data are expected such that the efficiency of many numerical software tools for Partial Differential Equations (PDEs) is restricted by the cost for memory access. In this article, we briefly discuss concepts for ...
متن کاملFEM Simulation of Dynamic Sliding of Faults Connecting Static Deformation Process to Dynamic Process
The objective of present study is to develop a finite element method (FEM) software system toward a large-scale computation of following seismic processes: (1) Accumulation of the stress around active faults in the crust, which is induced by a subduction of plates in a long time span (static deformation process); (2) Onset of an earthquake due to a dynamic sliding on the faults, which is induce...
