“…The structure of a SFG-CNTRC and load subjected to the plate In all distributions, the law of uniform distribution (UD) is the uniform distribution of CNTs in the cross-section of the plate, while the law of asymmetrical distribution (FG-V) or symmetrical distributions (FG-O, FG-X) is the dependence of the density of CNTs on the plate thickness variable. Accordingly, the mathematical model of the distribution of CNTs along the thickness direction of the plate is as follows [15], [16], [17], [21], [23]: In all distributions, the law of uniform distribution (UD) is the uniform distribution of CNTs in the cross-section of the plate, while the law of asymmetrical distribution (FG-V) or symmetrical distributions (FG-O, FG-X) is the dependence of the density of CNTs on the plate thickness variable.

This paper presents some results on the linear stability research of Stiffened Functionally Graded Carbon NanoTube-Reinforced Composite (SFG-CNTRC) plates under static in-plane loads by the Finite Element Method (FEM) and a new four-variable refined plate theory. The governing equations for the static buckling of the system are obtained by the new four-variable refined plate theory and FEM. The eigenvalue problem method was used to solve the equation to determine the critical force of the plates. A numerical example is compared with the results in another research to check the validity of the present algorithm. The influences of some factors such as plate theory, CNT distribution along the layer thickness, stiffener height ratio, and fiber orientation angle on the critical buckling loads and unstable regions are discussed.

“…This subsection is devoted to study static response of the cracked beam subjected to static force F and bending moments (18) by the well-known finite element method (FEM) [16][17][18]. The aim of this study is to verify the fact that multiple cracked beam could be repaired by applying bending moments (18) instead of using piezoelectric patches.…”

This paper addresses the problem of repairing multiple cracked beams subjected to static load using piezoelectric patches. First, the problem is formulated and solved analytically for the case of two cracks that results in ratio of restoring moments produced by employed piezoelectric patches. Since the ratio is dependent only on crack positions but not their depth, the result obtained for case of two cracks has been extended for the case of multiple cracks. This proposition is then validated by finite element simulation where repairing piezoelectric patches are replaced by mechanical moment load equivalent to the restoring bending moments produced by the piezoelectric patches. The excellent agreement between analytical solution and numerical simulation results in case of single and double cracks allows making a conclusion that a piezoelectric patch could productively repair a cracked beam by producing a restoring moment due to its piezoelectricity. Thus, the problem of repairing multiple cracked beam using piezoelectric patches is solved.
