tailieunhanh - Thermomechanical transient analysis of a thick-hollow FGM cylinder

This paper presents an analytical and a numerical thermomechanical investigation of a thick-walled cylinder made of the functionally graded materials (FGMs). The hollow cylinder is subjected to a pressure and a thermal load and the properties of this material are varying across the thickness from the inner face that is a ceramic to the outer one which is a metal. | Nội dung Text Thermomechanical transient analysis of a thick-hollow FGM cylinder Engineering Solid Mechanics 4 2016 25-32 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Thermomechanical transient analysis of a thick-hollow FGM cylinder Behrouz Takabi Texas A amp M University Department of Mechanical Engineering 3123 TAMU College Station TX 77843 United States ARTICLE INFO ABSTRACT Article history This paper presents an analytical and a numerical thermomechanical investigation of a thick- Received 6 April 2015 walled cylinder made of the functionally graded materials FGMs . The hollow cylinder is Accepted 10 October 2015 subjected to a pressure and a thermal load and the properties of this material are varying across Available online the thickness from the inner face that is a ceramic to the outer one which is a metal. After 11 October 2015 Keywords validating the current results by the analytical results the thermomechanical behavior of the FGM cylinder in the transient condition is investigated and the hoop and radial stresses and also Hollow cylinder temperature distribution are reported. The results reveal that the use of FG material causes a Numerical solution decrease in the stress thus it significantly improves thermomechanical behavior of the Transient domain thanks to using FG materials.

Introduction Nowadays functionally graded materials FGMs are playing an important role in the design of complicated and modern structures. FGMs have a
