In this paper we extend the phase-field model of crystallographic slip of Ortiz (1999 J. Appl. Mech. ASME 66 289–98) and Koslowski et al (2001 J. Mech. Phys. Solids 5

The elevation of Great Salt Lake (GSL) has a great impact on the people of Utah. The flood of GSL in 1982 has caused a loss of millions of dollars. Therefore, it is very important to predict the GSL levels as precisely as possible. This paper points out the reason why conventional methods failed to describe adequately the rise and fall of the GSL levels – the long-range dependence (LRD) propert...

به منظور ساخت، راه‌اندازی و عیب‌یابی مقدماتی چشمه پنینگ داخلی سیکلوترون 10IRANCYC، یک مگنت الکتریکی دوقطبی با میدان مغناطیسی در حد امکان مشابه مرکز مذکور طراحی ساخته شد. این الکترومگنت که دانشکده فیزیک دانشگاه تهران شد، قادر است بزرگی 7000 گوس را محل استقرار (منطقه‌­ای شعاع 15 میلی‌متر مگنت) آسانی بدون نیاز خنک‌سازی تأمین کند. دست‌­یابی 1/1 تسلا نیز استفاده از برای مدت چند دقیقه امکان‌­پذیر است...

An X70 natural gas pipeline steel that is being considered for blended gas/hydrogen service was evaluated in a high-pressure hydrogen environment. Fracture toughness testing and fatigue crack growth rate were conducted according to ASTM standards the results are presented context of ASME B31.12 qualification. While reduction fracture observed, behavior within acceptable bounds service.

Subsea processing of oil/gas is performed by production system facilities, which are linked into a complete subsea connectors. High reliability and long service life the connectors, defined strict requirement deepwater oil fields, raise challenge design structure components to ASME-VIII code has been applied. The theoretical problems main parameters connector's hub detailed in this paper compar...

Abstract In the field of bioplastics, complete kinetic models are rare but needed for industrial scale‐up. Herein, a model is developed to describe behavior robust and nontoxic guanidine carboxy Zn complexes in lab‐scale ring opening polymerization (ROP) l ‐lactide, mimicking melt presence co‐initiator. The includes inter‐ intramolecular transesterification random chain scission, considering si...

The problem of reflection and refraction of antiplane shear (or magneto-elastic) waves at the interface between two ferromagnetic half-spaces with slipping contact (vacuum gap) is studied for waves propagating normal to the direction of the applied external magnetic field which is assumed to be parallel to the interface. We show the existence of new waves that are localized near the interface b...
