It is more conveniently and less affected by topography.
FLAC3D can simulate the creep properties of the material which is related to the time.
Due to poor mechanical properties of rock, large rock deformations occur easily.
In summary, through the above modeling requirements, a three-dimensional tunnel model (Fig.2) is established, containing 37,335 units and 40,384 nodes. 3.3 Calculation parameters selected Rock relaxation and destruction after tunnel excavation is a dynamic process, affecting by many factors and complex mechanism of action.
Considering structural surface, interlayer and other uncertainties inside the rock, its mechanical properties are very different from experimental rock mechanical parameters.

At present, the quality of resistance spot welded joints is mainly determined through a test of its mechanical properties.
Therefore, it has important engineering significance to comprehensively study the impact of different welding parameters on mechanical properties of resistance spot welded DP steel joints, find the optimal welding parameters, determine the most intuitive control factors of the mechanical properties, establish quality evaluation model.
Sun et al[11] (2007) studied the corresponding relationship between metallographic structure, mechanical properties and welding parameters of the 1.2 mm thick magnesium alloy resistance spot welded joints.
In fact, welding parameters includes welding current, welding time, welding pressure, welding environment, cooling environment, etc., each parameter change will affect the mechanical properties of joints, it is not limited to current changes, and current changes is not the only or direct cause of nugget change.
The researches mainly focused on effects of welding parameters on nugget size, mechanical properties (tensile-shear load, failure energy, failure modes, fatigue, etc.) and microscopic characteristics (structure, microstructure, micro hardness) of joints, and identifying the control factors of resistance spot welded joints.

The mechanical properties firstly increased with the BMH content and then rapidly decreased.
Thereby the mechanical properties was increased in a certain range.
So that the mechanical properties of film becomes worse too.
These results suggested that the addition of inorganic BMH particles had adversely affected the film optical properties.

The properties of this layer are very crucial for the mechanical behavior of the component [20].
The discharge mechanism of EDM is somewhat complex and affected by other factors that bring considerable difficulties to detection and control, such as cavitation, adhesion, and short-circuit phenomena [26].
The main aims of this work are to design and plan an experimental and theoretical investigation to study the effects of EDM machining parameters on the workpiece material mechanical properties.
The tested mechanical properties and the Rockwell hardness test results are given in Table 1.

Recently, researchers draw more attention to basalt fiber due to its excellent mechanical properties, good thermal stability, and relatively low cost [4-6].
Some papers dealt with the introduction of basalt fiber for improving asphalt [7-8], while the detailed rheological properties and the regression relation between temperature and rutting factor are still poorly understood.
In this paper,we tested the rheological properties of asphalt mortar with different ratio of basalt fiber.
Results and discussion The rutting resistance properties of asphalt mortar were obtained by DSR testing.
It clan also be seen that the rutting factors rapidly decreases with the constant rise of the temperature in Fig. 4.

However polyamide 6 is highly hygroscopic and the mechanical properties of materials are reported to be degraded by water absorption.
However polyamide 6 is highly hygroscopic and the mechanical properties of materials are reported to be degraded by water absorption[2].
As an application of CFRTP becomes more extensive in the future, the usage environment also becomes diversified and it can be considered to be affected by various environmental factors.
In addition, when exposed to high temperature environments, it is wellknown that water absorption properties of FRP are affected by the damages such as cracks, and dissolution of resins[5].

Some sheets were subsequently cold rolled 10–20% to compare the mechanical properties with those of the commercial strengthened grades.
Introduction Ultrafine-grained (UFG) materials have been studied extensively in laboratory tests due to their promising mechanical properties.
Sheet thickness affects slightly the self-cooling rate, but it was found that the mechanical properties are not sensitive to that.
The reversion annealing of 45CR sheets at 695°C followed by water quenching showed that the decrease in ts from 65 to 6 s did not affect the tensile properties.
