Reflection of Plane Wave at Traction-Free Surface of a Pre-Stressed Functionally Graded Piezoelectric Material (FGPM) Half-Space
This paper is devoted to study a problem of plane waves reflection at a traction-free surface of a pre-stressed functionally graded piezoelectric material (FGPM). The effects of initial stress and material gradient on the reflection of plane waves are studied in this paper. Secular equation has been derived analytically for the pre-stressed FGPM half-space and used to show the existence of two ...
متن کاملModeling Bamboo as a Functionally Graded Material
Natural fibers are promising for engineering applications due to their low cost. They are abundantly available in tropical and subtropical regions of the world, and they can be employed as construction materials. Among natural fibers, bamboo has been widely used for housing construction around the world. Bamboo is an optimized composite material which exploits the concept of Functionally Graded...

متن کاملR-curve and strength behavior of a functionally graded material
The effects of loading conditions, specimen size and metal particle size on the crack growth resistance curve (R-curve) and residual strength of a ceramic-metal functionally graded material (FGM) are studied based on the crack-bridging concept. It is found that the FGM exhibits strong R-curve behavior when a crack grows from the ceramic-rich region toward the metal-rich region and the residual ...
متن کاملحلیل تنش وپیش بینی رشد ترک در پوششهای نازک (fgm (functionally graded material تحت بار ترمومکانیکی
در سال های اخیر با توسعه موتورهای پرقدرت صنایع هوافضا، توربین ها و رآکتورها و دیگر ماشین ها نیاز به موادی با مقاومت حرارتی بالا و مقاوم تر از لحاظ مکانیکی احساس شده است. پیش تر در صنایع هوافضا از مواد سرامیکی خالص جهت پوشش و روکش قطعات با درجه کارکرد بالا استفاده می شد. این مواد عایق های بسیار خوبی بودند ولی مقاومت زیادی در برابر تنش های پس ماند نداشتند. تنش های پس ماند در این مواد مشکلات زیادی...
