[ 1 ] - بررسی پارامترهای موثر بر آسیب های وارده به ساندویچ پنل کامپوزیتی در حین فرآیند سوراخکاری
هدف از انجام این تحقیق یافتن بهترین شرایط ماشینکاری و ایجاد سوراخ در پنل های ساندویچی کامپوزیتی با استفاده از تعریف فاکتورهای تورق و الیاف برش نخورده می باشد. برای این کار دو قطعه ساندویچ پانل از جنس اپوکسی کولار با هسته های چوب بالسا و فوم پی وی سی را با مته هایی با قطرهای مختلف و سرعتهای چرخشی و نرخ تغذیه متفاوت در سه سطح سوراخ کاری می نماییم. با استفاده از تکنیک عکسبرداری دیجیتال که راهکاری ...
[ 2 ] - Fracture Analysis of Externally Semi-Elliptical Crack in a Spherical Pressure Vessel with Hoop-Wrapped Composite
In this paper the effect of composite hoop-wrapped on stress intensity factor for semi-elliptical external crack which located in spherical pressure vessel, were investigated through the Finite Element Analysis. In order to find the effect of some parameters such as composite thickness and width, internal pressure and crack geometry, comparisons between different cases were done and discussed i...
[ 3 ] - Three-Dimensional Finite Element Analysis of Stress Intensity Factors in a Spherical Pressure Vessel with Functionally Graded Coating
This research pertains to the three-dimensional (3D) finite element analysis (FEA) of the stress intensity factors (SIFs) along the crack front in a spherical pressure vessel coated with functionally graded material (FGM). The vessel is subjected to internal pressure and thermal gradient. The exponential function is adopted for property of FGMs. SIFs are obtained for a wide variety of crack sha...
[ 4 ] - Edge Crack Studies in Rotating FGM Disks
This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...
[ 5 ] - Impacts of Building Insulation on Energy Consumption in Different Climates of Iran: A Cost Analysis
One of the most important energy-saving of building is suitable choice of insulation with regard to the climatic conditions of each region. In this study, the effects of building insulations approved by the Research Center of Way, Housing and Urban Development with regard to the cost of insulation on energy consumption in the region of Yazd, Tehran and Tabriz was evaluated by software Energy Pl...
[ 6 ] - Thermodynamic and Kinetic Investigations of Corrosion Inhibition Behavior of 2-MBT on Steel at a pH of 8
Corrosion results in hazardous and expensive damage to pipelines, vehicles, water and wastewater systems, and even home appliances. One of the most extensively practical methods for protecting metals and alloys against corrosion is to use organic inhibitors. The inhibition capability of 2-Mercaptobenzothiazole (2-MBT) against the corrosion of carbon steel in a 2 M NaCl solution was examined by ...
