چکیده
|
Traditional engineering materials lack the necessary properties that are needed in aerospace as well as other modern industries. in order to address the aforementioned problem, a number of different materials are used in concert. with the help of functionally graded material, all the necessary characteristics can be achieved. a fast transition between two different materials can lead to debonding, thermal stresses, residual stresses, and stress concentrations; a gradual change in material properties might mitigate these problems. this work provides a comparison of the analytical solutions for the deflections in two dimensional functionally graded taper beam (2d-fgtb) under a uniformly distributed load, adapting reddy’s higher-order shear deformation theory. all the material properties of the beam are graded along the thickness and length dimensions using the power-law formula. the thickness of the beam is assumed to change linearly along its length. equations of motion are derived based on hamilton’s principle and navier’s solutions. a parametric investigation is conducted to explore the effects of various material and geometrical parameters on the mechanics of 2d-fgtb. these parameters are found to be very significant in studying the static responses of 2d-fgtb.
