“…The advantages of using the damping capacity of thermoelastic martensite in shape memory alloys is discussed in [10]. In [11,12,13,14] martensitic SMA sheets were embedded into Glass Fiber Reinforced Polymer (GFRP) beams to passively enhance the damping of the system. While the concept of hybridization for enhancing the damping of the structures dates back to 40 years ago [15], SMA hybridized systems are considered as newcomers in this field.…”

This article investigates the efficiency of hybridizing composites with thin layers of martensitic shape memory alloys for improvement of damping. The non-linear damping behaviour of martensitic shape memory alloys is simulated using a modified version of Masing’s rules. The model was implemented in a user subroutine of a finite element code, and validated by a numerical simulation of experimental hysteresis loops at different maximum strain amplitudes. The experimental free decay of hybridized glass fiber reinforced polymer beams was simulated using the finite element model, including the validated model of the investigated materials. The amplitude-dependent damping of the hybrid beams in free decay was reproduced successfully in the numerical analysis and it was proven that the hybridization technique is efficient for improvement of damping.

“…Despite several explorations on forced vibration analysis of SMA hybrid composite plates such as [15][16][17][18][19], nonetheless yet there are rare publications on dynamic investigation of SMA hybrid composite beams. In this regard, Ghomshei et al [20] examined the transient response of thick elastic beams with an embedded SMA layer using high order shear deformation theory.…”

A comprehensive study is provided to compare the results of layer-wise theory (LWT) with one of the renowned equivalent single layer beam theories (ESLs) known as First-Order shear deformation beam theory (FOBT) on the study of transient nonlinear dynamic response of an SMA reinforced composite beam. Considering von Karman strain-displacement formulations, the governing equations of forced vibrations under transient impulsive loads are formulated by LWT and ESL methods. In order to simulate the constitutive behavior of SMA wires, the 3D SMA model developed by Panico and Brinson is adopted and reduced to a 1D model which enables one to reproduce pseudo-elastic (PE), martensite transformation/orientation and in particular ferro-elastic (FE) effects. General transient transverse loading is considered and the governing equations are discretized by combined method of differential-integral quadratures (DQ-IQ). Based on Newmark time marching technique, an incremental solution algorithm is developed for the problem in which nonlinear governing equations are solved by Newton-Raphson method. The results are assessed by comparing with available literature. Moreover, the FOBT and layerwise solutions are compared with each other and the effects of layup geometry and boundary conditions upon the composite beam responds are explored. The influence of volume fraction of SMA-wire reinforcements and the FE/PE behaviors of the wires upon the diverging results of FOBT/LWT analyses are studied in detail.

“…weight, high strength, fatigue resistance, as well as corrosion resistance. Besides, its cost is lower than that of aramid fiber reinforced plastic reinforcement (AFRP) [6][7][8]. Accordingly, UHPC is used rather than ordinary concrete [9] and combined with GFRP to form a novel type of composite beam to enhance the rigidity and durability of the structure, as well as to enhance the durability of ordinary concrete structures in marine engineering.…”

GFRP and UHPC were combined into a new composite beam, which was applied to ocean engineering to enhance the durability of ordinary concrete structure. To enhance the stiffness and durability of composite beam and lower the cost of structure, prefabricated construction technology was adopted to reserve holes for pouring UHPC. Through the quasi-static test of prefabricated GFRP-UHPC composite beams, the interface between concrete and GFRP was monitored using piezoelectric smart aggregate. The damage index was obtained in accordance with wavelet packet energy analysis theory to examine the interface damage of prefabricated composite beams. Experimental results show that active monitoring of assembled GFRP-UHPC composite beams with piezoelectric smart aggregate can effectively reflect the degree of interface peeling damage of composite beams. The monitoring results reveal that interface damage of specimens with reserved continuous holes is less than that of specimens with reserved discontinuous holes. Moreover, peeling damage will occur not only between GFRP and UHPC, but also at the interface between concrete and UHPC.
