A crystallographic homogenization procedure is introduced to the conventional static-explicit and dynamic-explicit finite element formulation to develop a multi scale – double scale – analysis code to predict the plastic strain induced texture evolution, yield loci and formability of sheet metal. The double-scale structure consists of a crystal aggregation – micro-structure and a macroscopic el...
The locking compression plate fixation treatment for the unstable sacral fractures is simple and effective, with less trauma and complications. Some locking compression plate parts have been made of high-strength Plate manufactured by hot stamping process since the demand for lightweight biomedical materials. Finite Element (FE) method of One-Step inverse forming based on deformation theory is ...
the use of twb has been developed in automotive industries because of it’s advantages such as reduction in weight, cost and fuel economy of vehicles. the main objective of the peresent work is to study the effects of weld zone, diffrence in surface coating and thickness ratio on the formability of twb composed of aisi 304, spcc and if steel sheets. it was found that the narrow weld zone has lit...
طراحی آزمایش با تعیین اهداف یک آزمایش و انتخاب فاکتورهای فرآیند برای مطالعه آغاز می شود. در واقع یک طراحی آزمایش، جزییات برنامه یک آزمایش را قبل از انجام آن، نمایش می دهد. یک طرح آزمایش مناسب، میزان اطلاعاتی که می تواند از یک تعداد معین آزمون به دست آید را بیشینه می کند. رویه جواب، از روش هایی است که برای به دست آوردن بهینه خروجی یک فرآیند یا سیستم مورد استفاده قرار می گیرد. در واقع رویه جواب ن...
in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...
