“…Various analyses of mechanical response of viscoelastic structures have been developed [1][2][3][4][5][6][7][8][9]. However, they fail to describe accurately global and through the thickness deformation and stress distributions because the transverse shear deformation effect is not considered adequately.…”

Time-dependent responses of composite plate are investigated based on efficient higherorder plate theory. The constitutive equation of linear viscoelastic materials, expressed as a Boltzmann superposition integral equation, is simplified by the convolution theorem of Laplace transformation. Hence, the computational resource can be saved significantly. A triangular bending element based on an efficient higher-order plate theory is applied to the viscoelastic composite plate. To pass the shear patch tests in all configurations, a modified shape function derived by Specht has been employed. To demonstrate the element and compare with other elastic and viscoelastic theories, the static bending problem under sinusoidal loading is considered, the material properties of graphite/epoxy GY70/339 are used to describe the viscoelastic responses like creep strain and relaxation stress. The present research provides an accurate and efficient tool for time-dependent problem of laminates.

“…To explore the hygrothermal-viscoelastic behaviors of composites materials, the constitutive equation in timedependent integral form is employed. [14][15][16][17][18][19][20][21][22][23][24][25] Yi and Hilton 17 explored the hygrothermal effects on viscoelastic behaviors of several composite materials. Marques and Creus 22 examined viscoelastic graphite/epoxy laminated plate and shell structures under hygrothermalmechanical loading with finite element method (FEM) formulation for nonlinear geometrical problem.…”

In the present study, the viscoelastic analysis is investigated for composite laminated plates using a smoothed finite element method called cell/element based smoothed discrete shear gap method. Moreover, the hygrothermal effects is considered on the viscoelastic responses of composite laminated plates. The first-order shear deformation theory is employed due to its simplicity and accuracy. With the help of the convolution theorem in Laplace transformation, the complex stress-strain relationship in integral form is simplified to linear in transformed domain. Therefore, all computing procedures are performed in the transformed domain and then, using inverse techniques (Fast Fourier Transform) to converted back to the real-time domain. The study provides an effective computational tool to analyze the viscoelastic response of laminated composite taking into account the influence of the time and hygrothermal effects.
