“…However, for the asymmetric bifurcation, the arch may exhibit one of the asymmetric deformations shown in figure 1b. Studies on the symmetric snap-through and asymmetric bifurcation of homogeneous macro/micro/nanobeams have been largely reported in the literature, and the influences of the initial arch rise, beam thickness, residual axial force, uniform temperature variation, size effect and surface effects have been systematically investigated [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Recently, functionally graded materials (FGMs) have been proposed to be used in MEMS [22,23] for their combined properties of improved stress distribution, enhanced thermal resistance and high fracture toughness [24,25].…”

“…In particular, curved micro-beams tend to unveil snap-through instabilities and symmetric/nonsymmetric buckling behaviors. [23][24][25][26][27][28][29][30][31][32][33] In this article, the influence of SQFD on oscillations of a slightly curved micro-beam is considered. The initial shape of the beam is assumed to have a sinusoidal profile.…”

“…Moghimi Zand (2012) also developed a finite element model and found the significant inertia effect on the dynamic snap-through behavior. Medina et al (2012Medina et al ( , 2014a examined the symmetric snap-through buckling and the asymmetric bifurcation of an electrostatically actuated mircobeam with/without residual stress. They derived the criteria of symmetric snap-through and symmetry breaking for quasi-static loading conditions.…”
