Abstract:
In this thesis, an analytical method is presented to investigate the steady state thermal and mechanical stresses of a thick hollow infinite cylinder made of porous piezoelectric that composed of functionally graded materials. So, according to the thermal and mechanical loads on internal and external surfaces of infinite cylinder, the porosity, temperature and material property distribution are considered as non-symmetric, two-dimensional (radial and circumferential) variables. The approach is presented to investigate this problem, by employing the method of separation of variables, Euler equations and complex Fourier series. Firstly, the governing equations of problem are extracted and then, analytically solved by using MATLAB software. Finally, the temperature changing, displacement field, electric potential and radial and circumferential stresses are studied; therefore, the obtained results are verified by using the available data in literature
