These factors increase the difficulty of analysis.
As the mechanical properties of adhesive are different at high strain rates, the failure parameters for analyzing adhesive joints should be based on experimental results at different strain rates.
As adhesives are polymer materials with significant viscoelastic characteristics, strain rate has obvious effect on mechanical properties of adhesive.

Pulsed current welded joints have given superior mechanical properties comparative to continue current welded joints.
This often results in inferior weld mechanical properties and poor resistance to hot cracking.
This zone is known as heat affected zone (HAZ).the unaffected base material is that the portion of the base material wherein the welding heat did not exceed the minimum required to affect its structure or properties.
Therefore the heat transfer and fluid flow in the weld pool can significantly influence factors such as weld pool geometry, temperature gradient local cooling rates and solidification structure.
(i) Pulsed current welding is found to be beneficial to enhance the mechanical strength of welded joints and mechanical properties of pulsed current welded joints are superior compared to the continuous current welded joints.

The recent development in FEA of SLJs is described with particular reference to three major factors that influence the success of adhesive bonding technique: failure mechanism, environmental effects and mechanical behavior.
The increasing complex joint geometry and its three dimensional nature combine to increase the difficulty of obtaining an overall system of governing equations for predicting the mechanical properties of the adhesively bonded joints.
Using 3D FEA, the present author and coworker [43] studied the influence of adhesive properties on the transverse free vibration characteristics of single lap-jointed cantilevered bonded beams.
The results showed that the strength of the adhesive has a very significant effect on the modal properties of the even modes of vibration but an insignificant effect on the modal properties of the odd modes of vibration.
However, accurate and reliable modelling of adhesively bonded SLJs is still a difficult task as the mechanical behaviour of these joints is not only influenced by the geometric characteristics of the joints but also by different factors and their combinations.

Liu Bailing [7] studied the biodegradation of PVA and its affecting factors and the results showed that molecular weight, crystallinity of PVA have a decisive effect on its biodegradability.
The effects of starch content, plasticizer content and mixing conditions on the processing temperature, melt flow rate and mechanical properties of PVA/Starch film were investigated.
Best mechanical properties were measured when the starch content was 40%, water content was 33% and plasticizer was 60 phr.
The strong hydrophility of starch affects the blend properties, so that the mechanical performance and waterproof performance of starch-based biodegradable plastic is poor.
The results showed that esterified starch film’s mechanical properties could reach application requirement when PVA was 30%, glycerol was 10%, coupling agent was 3% and glass fiber was 7%.

The effect of friction and wear, the mechanical structure and operation conditions on accuracy recession of numerically-controlled machine tools were described and commented as the key point.
Many scholars at home and abroad have made studies in many aspects about what affects the accuracy recession of the numerically-controlled machine tool, however the basic theoretical research is also imperfect so far.
And the real measure showed that the dynamic changes of the accuracy could be analyzed precisely with comprehensively considering the geometrical and physical factors, which influenced the accuracy recession.
Apart from the impact of above mentioned friction and wear and the mechanical structure, CNC machine tools are also affected by operation conditions in different working conditions.
At present, the main deficiency of the research on accuracy recession lies in: that firstly, in the study of the influence of the friction and wear on the accuracy recession, the research on the influence of the physical properties related to the contact layer in the part of the conjunction, including microhardness of the surficial layer, internal stress, the degree of cold hardening, lubrication conditions of the boundary and so on, on wear properties is not sufficient; In addition, researches mainly adopt the method of experiments, but experiments will cause a large consumption of manpower, financial resources and material resources and the limit conditions of the experiment are numerous.
