Finite Element Analysis of Rotating Truncated Functionally Graded Conical Shell



Functionally graded material (FGM) is popularly recognized as the promising materials for modern engineering applications, which gained attention of researchers due to its composition design and mechanical behaviour. FGM is most suitable choice as a structural material for conical pressure vessel and requires detailed analysis for its mechanical behaviour.



The design optimization of the rotating truncated conical shell made from FGM subjected to internal pressure (variable and constant) using Finite Element Method.



Using a commercially available finite element code, the effect of various parameters (such as cone angle, internal pressure, and angular velocity) on truncated conical shell was analyzed. The material properties and composition vary along the radial direction according to the exponential function.



Under the chosen circumstances 10⁰ cone angle, 4-12MPa internal pressure, and 50 rad/sec rotational velocity were found most suitable.



The results also showed that chosen parameters (such as, cone angle, internal pressure, and rotational velocity) is significantly influencing the stresses working on conical shell. This requires careful selection while designing the conical pressure vessel. These optimization results are helpful for research community to design a conical shell pressure vessel using FGM.
