The plastic behavior of materials depends on their strain rate sensitivity. The main objective of this paper is the analysis of the effect of strain rate sensitivity on plastic behavior of cylindrical shells under internal pressure loading and hence a large number empirical tests have been conducted on aluminum cylindrical shells. We have also manufactured and used a hydrostatic test machine to...

The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

With the complexity and amount of information in a wide variety of comparative performance reports in poultry production, making a decision is difficult. This problem is overcomed only when all data can be put into a common unit. For this purpose, five different decision making analysis approaches including  Maximin, Equally likely, Weighted average, Ordered weighted averages and Technique for ...

The finite element method (FEM) can be applied to practically analyze the tall buildings in which the shear walls are used to resist the lateral loads. Accordingly, a variety of displacement and strain-based as well as frame macro elements have been proposed for analysis of the tall buildings. With respect to application of the lower order plane stress elements, analytical problems may arise wi...

قرن هاست که از تخمیر برای حفاظت، بهبود کیفیت و یا اصلاح عطر و طعم حبوبات، میوه ها، سبزی ها، شیر و گوشت استفاده می شود. تاریخچه ترشی و شوری در ایران به زمان قوم ماد بر می گردد، در حالی که از عمر تولید صنعتی ترشی و شوری در ایران تنها70 سال می گذرد. سالاد زمستانه در واقع نوعی شوری تهیه شده از سبزی های مختلف است که در ایران و بخصوص در خراسان مصرف می شود. هدف از این پژوهش بررسی اثر سطوح مختلف شلغم ف...

Fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. Micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). It is well known that the structure and prope...

رها شدن گاز so2 در اثر احتراق سوخت های فسیلی یکی از علل اصلی آلودگی زیست محیطی و بیماری های تنفسی می باشد. عمده ترین ماده گوگردی موجود در نفت خام و برش های آن به صورت دی بنزوتیوفن و مشتقات الکیله آن می باشد. در گوگردزدایی زیستی، حذف گوگرد از برش های نفتی با استفاده از باکتری ها توسط محصولات ژن هایabc dsz که اولین بار از باکتریrhodococcus erythropolis strain igts8 جدا شدند از طریق مسیرمتابولیکی ...

SnO2 nanoparticles have been synthesized via sol-gel method in different annealing temperatures. TEM, FESEM and XRD techniques have been used to investigate the structure and morphology of SnO2 nanoparticles. The XRD pattern analysis shows all samples are single phase. XRD patterns show as the annealing temperature increases, the peaks become sharper which is related to the increase in the crys...
