Mechanical strength is one of the key factors for clinical application of injectable carbonate apatite (CO3Ap) cement.
The mechanical strength properties were evaluated by diametral tensile strength (DTS).
In conclusion, revealed that Na CMC does not affect the mechanical strength of CO3Ap cement.
Key factors for a successful clinical application would require ideal materials which could mimic the native bone in both mechanical and osteogenic properties while also possessing good injectability [7-12].

Factors Affecting Fatigue crack growth in FS Welded aluminum 2xxx alloys.
The difference in mechanical properties of different joining processes is presented in Table 1-3.
A number of factors affect the size and distribution of different zones in the weld and consequently affect the fatigue crack rate in the joint.
The fatigue properties of FSW joints are largely influences factors such as process parameters, weld-joint orientation and design, stress ratio, residual stresses, test environment and post weld treatments etc.
Residual stresses and heterogeneous microstructure have been found to be the principal factors that affect the FCG properties as they cannot be avoided despite maximum control of other parameters.

Influence of Degree of Deformation on Anisotropy in Mechanical Properties in Wrought Magnesium Alloy ZK60 M.
However, wrought Mg alloys suffer from anisotropy in mechanical properties due to the basal texture formed after extrusion.
In addition to elemental alloying which affects the c/a ratio of the alloy and thus the activation of various slip systems and deformation twinning leading to the texture modifications, the degree of anisotropy in mechanical properties is affected by the degree of DRX.
Present study examines the effects of total degree of deformation on the mechanical properties and their anisotropy in as-extruded Mg alloy ZK60.
These factors lead to a lower compressive yield stress than the tensile yield stress in tension.

The difference between the values of macro- and micro-hardness may derive from factors such as grain boundaries.

Nondestructive testing is a field of study which covers: identifying the mechanical and physical properties of materials and structural components, detecting material defects and discontinuities, and measuring the geometric dimensions of objects without affecting their performance.
Introduction Nondestructive testing (NDT) is a field of study which covers: identifying the mechanical and physical properties of materials and structural components, detecting material defects and discontinuities, measuring the geometric dimensions of objects without disturbing the continuity of their structure or affecting their in-service properties.
One can use resistographic tests to preliminarily estimate the mechanical properties of wood on the basis of its internal defects.
The RM value depends on many factors, mainly on the variety of wood, the condition of the wood and the direction of drilling.
Summary There are many methods which can be used to nondestructively assess the physical and mechanical properties of historic wood in a structure.

The test, using orthogonal design, includes two factors and three levels.
The two factors are the content of boron and the content of carbon.
These results indicate that the chemical compositions are decisive factors in determining the mechanical properties of alloy under the same preparation conditions.

In terms of applied mechanics, it is especially interesting to study how hydrogen affects mechanical properties of structural materials put in contact with hydrogenous environments.
Alteration of Material Properties from Hydrogen Saturation Experimental research on how material properties change under the impact of various external factors is quite common in the mechanics of materials – like a well-known Ioffe diagram which indicates changes in ultimate and yield strengths of metals when temperature of specimen testing is lowered (Fig. 1).
It is obvious that registering how hydrogen affects properties of a material requires uniform distribution of hydrogen concentration over the cross-section of a specimen.
