Moreover, it must exhibit sufficient mechanical strength to provide structural support during bone growth and remodeling.
The microcracks should not affect (positively of negatively) the biological performance of scaffolds but they certainly reduce scaffold's mechanical properties.
Another important factor related to the quality of the produced scaffolds with regard to their potential in biomedicine is the size of the pores as well as their interconnectivity.

In order to achieve important properties of decorative Ni-Cr plating, i.e., oxidation resistance, beautiful appearance and good adhesion, surface of substrate was necessarily prepared under medium roughness and then it was pre-plated with the thickest Ni layer before Cr coating was applied.
The adhesion between the plating layer and substrate depends on mechanical interlocking, directly related to surface roughness of substrate [4].
Thus, nickel has higher atomic packing factor than chromium that results in lower diffusion of oxygen through the Ni pre-plating layer.
This might be from they lost mechanical interlocking from low surface roughness resulting in lower adhesion strength [12].
A medium surface roughness of substrate before coating was necessary for approaching mechanical interlocking between substrate and coating layer.

Investigations on its stiffness and hysteresis properties [2], roll-over shape [3–5], energy storage and return [6,7], dynamic behaviour [8], kinematics and kinetics [9–13] have been performed.
Evaluation of geometry and material properties: The inputs for the FEA included geometric and material properties of the SACH foot.
The shear modulus and the incompressibility factor for the model were evaluated from the uniaxial tensile and volumetric compression tests, respectively.
Hence, the modulus of the components that might affect the forefoot stiffness, in this case, the cosmetic foam and the pad, were improved in the first iteration of the design.
Stiffness and hysteresis properties of some prosthetic feet.

The grain size has a strong influence on the mechanical material properties.
Metallic parts with a severe nanocrystalline grain refinement in the near-surface area show many beneficial properties.
Such surface layers considerably influence the friction and wear characteristics of the workpiece in a subsequent usage as design elements working under tribological loads due to their extreme superplastic properties.
Introduction Nanocrystalline grains within the surface layers of metallic materials show beneficial properties such as combination of high strength and ductility, resistance to corrosion and high temperatures, improved fatigue behavior and extreme superplasticity [1].
L is the length of the test-line, z the number of lines, nk the number of intercepts the line makes at the grain boundaries and V the magnification factor of the micrograph. 25 test-lines each with a length of 10 µm are applied for the microstructural analysis.

The water supply trough was equipped with both mechanical and chemical filters - a gravel filter was inserted at certain distances for grasping mechanical impurities and absorption of substances that could serve as nutrients for algae and bacterial that would adversely affect water quality in the system and subsequently the state of the wooden structure.
Any mechanical impurities then remained at the bottom of the filling room and were no longer in the foundation system.
In the past, the moisture regime of the monastery was adversely affected by many inappropriate interventions that have compromised the state of its construction.
The phenomenon of moisture movement is extremely variable from case to case, depending on the specific features of the masonry: direction, quantity and continuity of water supply from ground, depending on seasonal and accidental factors, evaporation condition, thickness and arrangement of the bricks in the masonry, nature of mortar joints etc. [14].
The monitoring and deeper investigation of moisture transport phenomena are useful for the assessment of the efficiency of remedial technologies and also a for better approaching the real properties of building materials and, at the same time actual climatic conditions experienced on site.

Even a mechanical mixture of the hydroxides of aluminium and magnesium does not result in complete spinel formation [2] by calcination at 1400 to 1600ºC for 1 hour.
This may be attributed to a combination of factors like the decreased average diffusion path and seeding effect of nano-spinel formed by nano-alumina.
The physical properties (refer with: Table 2) shows improved sintering from 1350 to 1450ºC with iron oxide and nano-oxides in the mixes.

In the construction process of concrete, the air temperature and earth temperature are the main factors which influence the temperature field and temperature stress.
According to the parameters of Xiluodu spiral case concrete, the thermal parameters are listed in Table 1, and the mechanical parameters are listed in Table 2.

It gives the free mechanical boundary conditions in stress field calculation before interfaces are covered, and the mechanical boundary disappear after interfaces are covered.
Concrete strength significantly affects the temperature stress.

High voltage bushing is the core component of high-voltage wire inside high voltage switch cabinet, it is the main insulation when high voltage conductor was connected between high voltage switchgear, insulation quality of high voltage bushing will directly affect the overall insulation performance of high voltage switch cabinet and reliability of high-voltage switch cabinet’s operation [5,6].
To compare insulation properties of three type samples, voltage resistance and partial discharge of samples were tested by related equipments.

Although finite element and boundary element numerical method have been already put into solving intensity factor of fracture mechanics stress, the failure process and characteristic of specimen cannot be simulated [1-5].
Therefore, some mechanical behaviors due to the homogeneousness cannot be investigated in the course of concrete fracture.
