Exact solution for nonlinear thermal stability of hybrid laminated composite Timoshenko beams reinforced with SMA fibers

Thermal postbuckling analysis of anisotropic laminated beams with different boundary conditions resting on two-parameter elastic foundations

“…Let us assume that the first buckling mode is approximated by a polynomial of the sixth order, which satisfies the geometrical boundary conditions. According to previous research efforts (Sapountzakis and Dourakopoulos, 2010;Esfahani et al, 2013;Gupta et al, 2010;Asadi et al, 2014) the buckled shape should satisfy the geometrical (kinematic) boundary conditions so that the calculated buckling load is close to the true buckling load. However, in an ideal solution the buckled shape described by any chosen function should also satisfy the physical (static) boundary conditions.…”

“…Lee and Choi (1999) studied the thermal buckling and postbuckling behaviors of a composite beam with embedded shape memory alloy (SMA) wires using the finite element model in which the SMA wire actuators are modeled with the beam elements and the composite laminates with the shell elements. Asadi et al (2013Asadi et al ( , 2014 investigated the large amplitude vibration and nonlinear buckling of SMA fiberreinforced hybrid composite beams with symmetric and asymmetric lay-up using the Euler-Bernoulli beam theory and the nonlinear von-Karman strain field. When the EulereBernoulli beam theory is used for the buckling analysis of laminated beams, the buckling loads are overestimated, due to the consequence of neglecting the transverse shear strain and assuming that the plane normal to the beam axis still remains normal even after the deformation.…”

Nonlinear thermo-inertial instability of functionally graded shape memory alloy sandwich plates

“…In all of these studies, thermomechanical responses of SMA fibers have not been extensively investigated, except few attempts that have extracted the approximate curves from experimental results. A few studies have been developed by using the phenomenological model to express the constitutive characteristics of SMA fibers [35][36][37][38][39][40][41][42][43][44][45]. Roh et al [35] investigated the thermal snapping phenomenon in shell panels by the finite element method.…”

“…Cho and Rhee [36] introduced a nonlinear finite element approach for modeling the hybrid laminated composite shell reinforced by SMA fibers subjected to the thermomechanical loading. Nonlinear dynamic and stability responses of laminated composite beams containing SMA fibers were investigated by Asadi et al [39,40]. A study on the influence of SMA fibers on structural responses of hybrid composite plates was also conducted by Asadi et al [41].…”

Vibration analysis of self-healing hybrid composite beam under moving mass

“…The vibration analysis of SMA composite under impact loading was performed by Damanpack et al [6]. Recently, Asadi et al [7] studied on the post-buckling behaviour of hybrid composite beam. The post-buckling of composite beam for various volume fractions of SMA wires was drawn and compared.…”
