Experimental Modeling for the Compressive Strengthening Mechanism of an Al-Li / SiCp Composite

an investigation about the appropriate stochastic modeling framework for agricultural insurance pricing

با توجه به اینکه بیمه محصولات کشاورزی در ایران بیشتر جنبه ای حمایتی دارد و خسارات گزارش شده عموما بیش از حق بیمه های دریافت شده است، در این پایان نامه به جهت تعیین قیمت بیمه محصولات کشاورزی (گندم دیم) از فرآیندهای نوفه شلیک به عنوان مدلی مناسب استفاده شده است. بر اساس داده های صندوق بیمه کشاورزی از خسارات اعلام شده در سال زراعی 1388-1389 گندم دیم، در این پایان نامه حق بیمه خالص و ناخالص این محص...

MICROSTRUCURE AND STRENGTHENING OF Al-Li-Cu-Mg ALLOYS

A detailed quantitative model for the strengthening of monolithic alloys and composites due to precipitation strengthening, solution strengthening, grain and subgrain strengthening, strengthening by dislocations and load transfer to ceramic inclusions is presented. The model includes a newly derived description of the effect of a precipitate free zone (PFZ) around the reinforcing phase incorpor...

An Experimental Investigation During Micro Drilling of Hybrid Al/(Al2O3p+SiCp+Cp)-MMC onDeveloped ECMM Setup

This paper presents the effects of various parameters of fabricated electro chemical micro machining (ECMM) setup on machining response characteristics during micro drilling of Hybrid Al/(Al2O3p+SiCp+Cp)-MMC. AnECMM setup has beendesigned and fabricatedfor the purpose. Fabricated ECMM setup has different units such as mechanical machine unit, electrical power supply and control unit, electrolyt...
