In these applications, a full characterization of their mechanical properties including compressive strength and elastic modulus, at a wide range of strain rates is needed.
However, the most important factor affecting the compressive strength is its inhomogeneity, particularly the number and size of the non-uniform cells which result in local density lower than the average valued measured for the whole specimen.
A previous study suggested that, to evaluate effectively the mechanical properties of foam materials, the length of a specimen should be firstly determined.
Two factors may contribute to such phenomenon: friction effect between the specimen and bars and existence of weak deformation bands.
Two factors, which may contribute to such behavior, were presented.

Glass Fiber Reinforced Plastics composites have an increased application in recent days, due to its enhanced structural properties, Mechanical and thermal properties.
Introduction Glass fiber Reinforced Plastics (GFRP) are widely being used in the automotive, machine tool industry, aerospace components, sporting equipment’s [1] because of their particular mechanical and physical properties such as specific strength and high specific stiffness.
The full factorial design is the most efficient way of conducting the experiment for that three factors and each factor at three levels of experiments is used.
Hence as per Levelsfactor (factors to power of levels) formula = Levelsfactors , N = 33 = 27, N- number of experiments.

Design of Experiment: A Statistical Approach to Understanding Factors Influencing Surface Properties of sol-gel based Non-stick Ceramic Coatings.
Through Design of Experiment (DOE) a mathematical and statistical techniques can be used to design,build and evaluate effects of factors (process variables) and identify optimum condition of variables for desirable properties.
A 26-1fractional factorial screening design was performed with six experimental factors to investigate three responses (surface properties) of sol coatings are shown in Tables 1and 3 respectively.
Conclusion Design of experiment (DOE) was used as a prediction tool to determine the experimental process factors that could have influence on the surface properties of ceramic sol coatings.

For braided hollow profiles, however, technical possibilities to achieve process integrated adaption of a components’ mechanical properties are limited.
Adaption of the braid angle allows adjustment of the laminate’s properties in the entire cross section (to what extend depends on braid type and choice of materials), affecting the haul-off speed at the same time.
Uniform mechanical properties can still be achieved over multiple braid layers and appropriate offset angles between the layers (the mandrel cross section defines the rotation plane).
The remaining factors and interactions (not displayed) have only minimal impact within the specified factor levels.

The concentrations of AgNP affect physical properties of acrylic resin denture base [2,13].
The aim of this study was to evaluate the influence of the incorporation of prepared AgNPs on the flexural strength and dynamic mechanical properties of the dentures base acrylic resin.
