In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...
یکی از بارزترین مشکلات در زمینه موفقیت بنگاههای اقتصادی در تجارت الکترونیک، شکست خوردن بسیاری از تجار در این نوع تجارت می باشد، زیرا بسیاری از تجار فقط چون استفاده و دسترسی به اینترنت را راحت می دانند به این امر روی میآورند و نمی دانند ورود به این نوع تجارت شرایط و آمادگی های قبلی و همچنین روش های خاص خود را برای جلب مشتری دارد. لذا در این پروژه بر آن شدیم تا مدلی جهت امکان سنجی ایجاد یک سایت b...
In this article, a coupled computational framework is presented for the numerical simulation of mass transfer under the effects of natural convection phenomena in a field contains water-copper Nano-fluid. This CFD model is build up based on accurate algorithms for spatial derivatives and time integration. The spatial derivatives have been calculated using first order upwind and second order cen...
this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...
This study proposes an optimized model of a micro-energy network (MEN) that includes electricity and natural gas with integrated solar, wind, energy storage systems (ESSs). The proposed is based on hubs (EHs) it aims to minimize operation costs greenhouse emissions. research motivated by the increasing use renewable energies ESSs for secure supply while reducing environment effects. A general a...
