This is mainly caused by the lack of data in order to evaluate the process economically and differentiate it to other processes like arc and laser welding, also regarding technological factors.
Moreover, the absence of a liquid phase during the process leads to favourable seam properties, like enhanced fatigue properties [4-5] and formability [6].
In this way, FSW seams can exhibit outstanding mechanical properties.
For the referencing experiments, welds were produced with a conventional aspect ratio of the tool and the rotational speed was varied in order to display the effects on the resultant spindle torque, mechanical properties and seam appearance.

Introduction Time correlation characteristics of material mechanics performance is very important for the structure design, especially the long-term mechanical properties of accurate information is the basis of analyze the structural strength and life [1].
In the course of service of the building silicone sealant, stress relaxation (physical aging) also lead to its mechanical properties change, at a certain temperature and under long-term loading will exhibit its own creep characteristics.
Therefore, considering the time correlation performance of the building silicone sealant is very important, and fully grasp the mechanical structure adhesive properties of the time evolution, especially the evolutional law of mechanical properties changes with time and nonlinear viscoelastic and long-term mechanical properties of the building silicone sealant.
Therefore, load(stress) level is an important external factors influencing structural adhesive creep behavior, control load level is one of the important ways to prevent long-term creep failure for building silicone sealant.

Metamaterials are controlled arrangements of material structures in which their mechanical properties can be tailored by tuning their geometrical parameters.
These apparent properties are a function of the metamaterial topology and volume fraction [4].
Apparent mechanical properties of cellular solids are usually calculated from static simulations or experiments, including standard tensile, compression and bending tests.
Few works focus on the characterization of the mechanical properties of lattice-beams subjected to different loading conditions, which is the purpose of this work.
Then, the metamaterial synthesis approach used here enables the generation of beams with mechanical properties adjustable to a desired value.

Introduction Modern concrete research shows that the macroscopic mechanical properties of concrete are closely related to the mesoscopic internal crack development.
In long-term research process, concrete is always consider to be a macroscopic homogeneous continuous body, and difficult to reveal the relationship between the mechanical properties and internal structure, composition of the concrete.
Bazant [1] presented a micro plane model in 1705, the model indicates that the concrete damage and relevant to crack propagation path; Mohamed and Hansen [2] considered the randomness of the aggregate distribution matrix in their model, and used the distribution crack model to describe the unit tension damage constitutive; Ma [3], Li [4] and Peng [5] used the modal presented by Mohamed to simulate the meso-level mechanical properties of roller compacted concrete, and found that the mechanical properties of uniaxial tensile, compressive and splitting tensile are more consistent with the test results.
Tang [6] used the statistical mechanics to consider inhomogeneity of concrete materials and mechanical properties, and make component materials of the mesoscopic element mechanics properties satisfy the Weibull distribution.
