The current study is devoted to investigating the effect of elevated temperature on interlaminar stresses for different laminated viscoelastic structures and boundary conditions. Each structure considered consists of three laminated layers, where the core layer is made of plasticized polyvinyl butyral, which is a viscoelastic material, whereas both constraining layers are made of isotropic structural material silica float glass.

Finite element (FE) modeling is used to perform modal, harmonic, and transient analyses. The current viscoelastic composite model is compared to data in literature for verification purposes. Simply supported beam, cantilever, and simply supported plate are studied for temperature variation of 23, 40, 50, and 60 C. Modal analysis is carried out to find natural frequencies for all the structures considered.

The results obtained show that increasing temperature plays a significant role in reducing the natural frequencies in each structure as well as increasing the transverse deflections and decreasing the corresponding interlaminar shear stresses.

The literature does not contain a study on the influence of elevated temperatures on interfacial dynamic stresses in laminated viscoelastic structures.

Practical value. One of the main factors affecting the delamination process of composite viscoelastic sandwich structures is the interfacial harmonic shear stresses existing between layers. Hence, harmonic and transient analyses are performed to determine dynamic deflections and interlaminar shear stresses.
