Introduction Double L-ring 200 liters large barrel of materials is a large hollow blow molding products，such a large barrel of materials manufactured by extrusion blow molding method, Extrusion blow molding is the blow molding method for molding one of the three[5].
System design ideas According to the two L-ring drums of 200 liters of large material requirements, first in the three-dimensional modeling environment solidworks design 200 liters barrel three-dimensional model of large materials, then built by stacking three-dimensional stress analysis of materials bucket model, recycling the obtained analysis results to optimize the design, Optimize and verify whether the results meet the requirements, finally, there is then the optimized 200 liters of large material bucket drop test to verify the material barrel drop breakage, and ultimately determine whether the end of the design.

Thus, these papers can represent an useful link for passing throughout the full process in terms of changes on the mechanical properties of materials (integrating information available in [19, 20]).
As expected, a large number of standards already exist, dealing with ceramic materials and products.

Soundless Crack is widely used in stone exploitation, partly crack of brittleness materials such as rock and concrete, and backout of building in city.
In these engineering, we must drill many holes for loading Soundless Cracking Agents, but the drilling cost is expensive including human cost and materials cost, at the same time need much time to drill these holes.
If we can know the mechanics parameters of the materials, we can numerical calculation the failure process before drilling, rectify the planning distance between holes to gain the best cracking results.

In the design of piezoelectric actuator the concept of compliant mechanism combined with piezoelectric materials has been used to magnify either geometric or mechanical advantage.
The polarization of piezoelectric materials is considered to improve actuation since the piezoelectric polarization has influences on the performance of the actuator.

The research of two-dimensional (2D) materials deals with various topics, including condensed matter physics, electronic engineering, materials science, and chemistry, since graphene was mechanically peeled in 2004 by Geim and Novoselov [2].
Although there have been many studies on the melting process of BN materials, the melting mechanism of two-dimensional BN materials with a free surface under the influence of temperature has not been studied in detail.
