Nonlinear Forced Vibration of Curved Beam with Nonlinear Viscoelastic Ends

International Journal of Applied Mechanics, Journal Year: 2024, Volume and Issue: 16(03)

Published: Jan. 8, 2024

This article develops a mathematical formulation to investigate the nonlinear forced vibration of curved viscoelastic beam with boundary conditions around buckled position numerically, for first time. The integro-differential equation buckling problem and corresponding nonhomogeneous are discretized by differential integral quadrature method (DIQM) after that, they solved via Newton-iterative compute static deflection paths. By employing DIQM, linear is converted eigenvalue that easily. Galerkin technique implemented reduce partial governing dynamic into Duffing-type equation. Duffing periodic spectral differentiation matrix operators. Finally, pseudo-arc length continuation algorithm applied solve resulting from duffing Validation numerical techniques in solutions proved previous works. Parametric studies conducted deliberate influences amplitude initial curvature, axial load, support parameters on behaviors straight beams. It should be noted proposed computes both stable unstable solutions.

Chaos and bifurcation analyses of functionally graded composite spherical shallow shells reinforced with graphene nanoplatelets

Results in Physics, Journal Year: 2024, Volume and Issue: 58, P. 107461 - 107461

Published: Feb. 10, 2024

Functionally graded (FG) graphene nanoplatelets reinforced composite (FG-GPLRC) structures are expected to be greatly developed in engineering due their excellent mechanical properties. The nonlinear dynamic behaviors such as chaos and bifurcation particularly important. This article explores the dynamics of FG-GPLRC shallow shells with three different GPL distribution patterns under transverse in-plane excitation. effective material properties were calculated using an improved Halpin-Tsai model mixture rule. Using Hamilton's principle high-order shear deformation theory (HSDT) design a mathematical simply supported spherical shells. Numerical analysis shows that weight fraction, layer number, length-to-thickness ratio have significant effects on behavior. These parameters varying sensitivities patterns. X-shaped is more capable withstanding larger external excitation compared U-shaped O-shaped. O-type sensitive number. behavior two modes also after exceeding critical value. focuses providing theoretical guidance for practical by simulating complex excitations.
