It makes it possible for designers to join dissimilar materials and consolidate different parts [2] and provides stiffer assemblies and better load distribution.
To understand the asymmetric effect in mechanical properties of the substrates, steel and aluminium alloy are taken as the substrate materials in each joint separately.
The asymmetry in the substrate materials in SLJ is believed to be the cause of the variation.
As dissimilar materials are adopted in each SLJ, the different coefficients of thermal expansion between steel and aluminium alloy lead to non-ignorable internal stress when environment temperature changes, which is straightly applied to the adhesively bonded joint.

Composite materials are formed from two or more materials producing properties that could not be obtained from any one material.
One of the constituent materials acts as the matrix and at least one other constituent material acts as the reinforcement in the composite.

The fractional derivative model can describe the mechanical behaviors of viscoelastic materials in a very wide range frequency and need less model experiment parameters to fit experimental data[9], so the fractional derivative viscoelastic model has enough attention in recent years.
