Product factors.
The factors include; density, weight, geometric size, tolerance, shape and mechanical properties.
Product factors The equipment.
So, with both process and product factors in mind, the configuration model must have the ability to detect/ analyse the following eight factors: 1.
The mechanical handling properties of this product are 'weaker' than current films; • To make the new product cost effective the production rate is also required to be increased.

The fracture complexity could be affected by many reservoir and treatment parameters, such as fracturing fluid viscosity, modulus and possion’s ratio of the shale reservoirs, proppant properties and so on [5].
Among all the affective parameters, the stress anisotropy is the most effective and decisive parameter affecting the fracture complexity [6].
The mechanical behavior of the pore pressure cohesive element is defined in terms of a traction-separation law [17, 18].
In the following figures, the deformation magnification factor is taken as 400.

The influence of these mechanical treatments on the transition temperatures and the hysteresis evolution was also analysed by following the integrated intensity of the {220} reflection of the austenitic phase.
This property is due to the austenite-martensite phase transformation which can be induced thermally by a cooling or mechanically by applying a load.
For these alloys, transformation temperatures are of importance factor for the behaviour of the material and can be affected by several parameters (microstructural defects, grain size or residual stresses) [2].
In this study we propose to investigate on a copper based alloy the influence of the mechanical deformation by cold and hot rolling on the microstructure evolution by following the texture variation with the rate of deformation and how this modifies the characteristic transition temperatures.
This mechanical treatment thus introduces metastable residual martensite due to inter-and intragranular stresses generated by deformation incompatibilities between grains with different orientations and by transformation strains.

One critical issue is achieving proper dispersion of fine clay particles to improve flow properties [18].
Core themes include optimizing mechanical properties, rheological performance, and hygrothermal efficiency.
A review of literature on precast earthen systems suggests that stabilizer content, curing humidity, and demolding time are critical factors [31], but SCEC-specific data is still lacking.
Core research themes include optimizing mechanical and rheological properties, enhancing hygrothermal performance, and evaluating environmental benefits.

Surface quality is affected by various processing parameters and inherent uncertainties of the metal cutting process.
Surface roughness and dimensional accuracy are significant factors in predicting the performance of any machining operation.
Many of the properties of 7136 aluminum alloy are superior to other materials, including high strength to weight ratio, high wear resistance, low thermal expansion, corrosion resistance, durability, ductility, and conductivity, which make it a versatile material.
As to the productivity related to surface roughness, according to obtained data from the experiment, we found that the best ratio of these two factors is to the cutting regime: cutting speed at 530 m/min, feed per tooth at 0.14 mm/tooth and cutting depth at 4 mm, resulting a surface roughness of 0.212 μm.

The selection of appropriate mortar mixtures is an important research problem once four main factors should be considered in their design - durability, flexural resistance, compatibility and, consequently, economy.
In terms of physical properties, mortar samples were used for capillary water absorption determination – capillary coefficient in terms of initial capillary absorption velocity and the asymptotic value in terms of total capillary absorption [12, 13].
Lime-based mortars flow consistency seems to not be affected by the usage of waste fibers.
LF1, with 0,25% of waste fibers, presents one of the most well-adjusted mechanical behavior.

Continued progress has led to improved understanding of synthesis pathways and material properties, yet a comprehensive mapping between structure and performance is still evolving.
Each of these factors was shown to significantly affect the permeability and enantioselectivity of the resulting membranes.
The pH of the solvent was found to be the most influential variable, directly affecting electrostatic interactions between the enantiomers and the β-CD-COF surface.
The membrane also modulated the wound microenvironment by regulating inflammatory cytokines and growth factors.

If this TM steel is applied in hot-stamped automotive parts, it is likely that the mechanical properties of the parts will be affected by the cooling rate after hot-stamping, because the retained austenite characteristics and the matrix structure are controlled by the cooling rate.
In addition, the relationship between these impact properties and the metallurgical characteristics was determined.
The impact properties were evaluated by determining the upper-shelf Charpy impact absorbed value (US-CIAVs) and the FATTs of the specimens.
Tensile Properties.
Figure 5 shows the tensile properties of the TM steels for various post-austenitization cooling rates.
