Accurate eccentric impact analysis of the preloaded SMA composite plates, based on a novel mixed-order hyperbolic global–local theory

Experimental and numerical analysis of low velocity impact on a preloaded composite plate

“…A relatively small number of researchers have analyzed the behavior of preloaded structures subjected to low-velocity impact, the researchers studied experimental [6][7][8][9][10][11], numerical [12][13][14] both experimental and numerical [15][16][17] which discuss the impact response of different composite laminates. Some of these researchers focus on plates forced uniaxial or biaxial in-plane load, uniaxial tensile [7][8][9], biaxial tensile [11], uniaxial tensile and biaxial tensile-compressive (shear) [10] subjected to low velocity impacts.…”

Simulation of Eccentric Impact of Square and Rectangular Composite Laminates Embedded with SMA

“…However, the study on low velocity eccentric impact are still limited. So far, the study of low velocity eccentric impact has only been reported by Shariyat et al [11,12,13,14] in literature. First of all, they only investigated the low velocity eccentric impact analysis of rectangular laminated composite plates subjected to in-phase/anti-phase biaxial preloads (see reference [11]).…”

“…The results showed that the contact force and the absorbed energy will increase, and the failure will more likely occur in the low velocity eccentric impact. Furthermore, they further analyzed the accurate eccentric impact for composite plates with embedded the preloaded SMA based on a novel mixed-order hyperbolic global-local theory (see reference [14]). In their work, they propose a higher-order global-local hyperbolic plate theory including both odd and even functions to describe the general asymmetric displacement fields; and moreover, Shariyat and his co-workers have considered some other factors, such as the non-uniform and time-dependent distributions of the phases of the SMA wires and different contact laws for loading and unloading phases.…”

“…In Section 3, the modeling framework of the SMA reinforced square and rectangular laminated composite plate under low velocity central and eccentric impact are given. In Section 4, the impact responses of the rigid spherical indenter for the cases of low velocity central and eccentric impact are analyzed, and they are compared with the results of Shariyat et al (see [14]). Moreover, the damage morphology patterns of SMA reinforced square/rectangular laminated composite plates are also analyzed, and the lateral deflection histories of different impact points in the top/bottom layer SMAs and the composite plates are discussed.…”

A new approach for treating concentrated loads in doubly-curved composite deep shells with variable radii of curvature

“…As a function of the hypothesis of the theory under study the solutions can closely fit the original 3D shell or plate. In the recent literature http a huge amount of studies can be found about 2D theories for selected problems of engineering practices [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50].…”
