It is known in literature that different damage modes occur during fatigue life of composite materials.
For non-isotropic materials moduli need to be measured in different loading directions.

Polydopamine (PDA) materials also have attracted widely attentions since Messersmith etc. reported PDA material could firmly adhere to almost all surface of materials [14].
However, PDA materials, used to be filler to construct nanocomposite hydrogels, is still unexplored.

The material of piezoelectric ring stack is PZT-4, and the size of the piezoelectric ring is Φ10×Φ5×2.
The material of the back slab is stainless steel, and the material of the front slab and ultrasonic horn is made of titanium which has small density and high tensile strength and elastic limit.
And the error of simulation may be originated from the material parameters and structure sizes, or the simplified model.

The BLR behaviour of Mg-alloy is geometry and material dependent.
This means that, the configuration of the test sample, the compliance of the bolt/joint and creep response of the material under investigation play important role in determining the joint response under load and temperature.
These alloys, when bolted together with other materials at elevated temperature under load, loses fastener clamp load due to creep of the Mg-alloy component.
While t is the creep time, ni is the compressive creep parameter and ki is dimensionless constant that depends on the joint-to-bolt stiffness ratio of the couple, C in Eq. 4 is a temperature and specimen geometry dependent material constant.
