This research investigates the effects of cut-out on the dynamic behaviour of functionally graded carbon nanotube reinforced composite (FGCNTRC) plates. Finite element method (FEM) is utilized and SHELL181 type element of the ANSYS Workbench 17.2 program is utilized. To understand the vibration characteristics of the FG plates, various shapes of cut-outs such as triangular, square, rectangular, hexagonal, circular etc. are considered. For comparison, solid FGCNTRC plate is modeled and natural frequencies of plates integrated with cut-outs of different shapes are determined using free vibration study. The mode superposition method is used to address the harmonic response analysis problem keeping the damping ratio constant. The stress, phase changes and displacement responses for definite frequency ranges have been used to interpret the findings. To learn more about the effects of cut-outs on the dynamic response, the plates are designed considering various grading patterns. The findings show that the shape of cut-outs significantly affects the harmonic responses as well as the fundamental frequency of the FG plates and are also depending on the grading patterns of these plates.

Thermotropic yield characteristic of the ceramic–alloy composite beam induced by a unilateral heat source is investigated by using the Hamilton principle and the variation method based on the first‐order shear deformation theory. The mathematical essence of the yield problem of the composite beam is that the variation of the Lagrange function of the system to the space coordinates equals zero. The Tamura–Tomota–Ozawa model and the linear rule of mixtures are used to simulate the composite material properties of functionally graded material (FGM), and the constitutive equations are established with the linear hybrid hardening model. The von‐Mises yield condition is introduced to judge whether the beam enters the yield state. The governing equations are established by using the Hamilton principle and variation method. The thermotropic yield surfaces, the yield stresses, and the critical temperature rises of the yield functionally graded beam are obtained, and the deflections of the beam are calculated by analytical method. The results reveal that the yield interfaces, the yield stresses, the critical temperature rises, and the deflections of the beam vary with material parameters, geometric parameters, and so on.
