This is based on structural parameters and mechanical properties of components of a composite rope and conditions of its interaction with the structure, thereby increasing reliability and operation efficiency of the structure, in particular, the cable-stayed bridge.
Stay ropes are affected by the environment, wires corrode, and wind loads affect them.
The distribution of forces among the cables depends on the specified factors.
Since the mechanical properties and stay rope design are different and regular in orthogonal directions, the stay rope as a composite structure is orthotropic.
A model is created, a method for calculating a stress-strain state of an orthotropic composite tractive element is developed, with comprehensive consideration of its design, mechanical properties of its components, and given conditions for connection to the structure.

However, these properties also make them difficult to machine into a precise size and shape.
The materials properties are shown in Table 1.
The Range (“Delta”) shown in Table 4, represents the difference between the maximum and minimum values of S/N ratio at each level, describes the significance of each factor affecting the responses.
The “Delta” value is higher for most significant factors and its value decreases for less significant factors.
It means that all the factors affecting the surface roughness have been considered in the predictive model.

Alignment of reinforcement particles was observed to affect the fatigue behaviors of extruded composites strongly.
Interfacial reaction, in particular, can adversely affect the mechanical properties of the composite.
Fatigue behavior of particle reinforced composites depends on many factors, such as, matrix microstructure, volume fraction, and size of reinforcement particles, and the presence of inclusions in the matrix or defects such as particle clusters [11].
Fatigue crack growth and fatigue damage in unreinforced alloy and composites is significantly affected by R ratio.

EFFECT OF DIFFERENT SOLID AMOUNTS IN THE PHYSICAL AND
MICROSCOPICAL PROPERTIES OF SiC POROUS CERAMICS
Jerusa G.
Introduction The forming process is essential to determine the mechanical and microstructural properties of ceramic materials.
An increasing concern on the environment and the cost optimizing necessity that involve the different stages of the ceramic processing are factors that affect the choice of the correct forming process.
On the other hand, factors such as, availability, non-toxicity, besides inert properties must be considered when choosing the material to be used.
Both conditions of formation had their final properties influenced by foam presence and agglomerate formation.

The Composition of Slope Deformation Statistical Regression Model
Slope deformation was mainly affected by the material bulk density and mechanical properties of the slope itself.
On this basis, through the qualitative and quantitative analysis of high slope deformation monitoring data, aging, rainfall and temperature were the main external factors affecting the high slope deformation.
When the present factor became not significant as the introduction of factors, it would be removed out of the regression equation.
Slope Deformation Impact Analysis of Each Component. (1) Aging component Aging was the main external factor affecting the high slope F59 fault vertical displacement.
It further illustrated aging was the main factor to affect high slope deformation.

Results and Discussion
There are many factors to affect the polymerization process of core-shell latex particles, and the polymerization temperature, initiator dosage and reaction time on the stability of polymerization system is particularly important.
The chemical connection in core-shell interface is very important for improving the toughness of brittle material,however the key factors affecting the chemical connection is the intruduction of grafting agent.
In orthogonal test of three factors five levels, change factor were polymerization temperature, initiator dosage, and reaction time, which logogram as A, B, C, respectively.
The effect of three factors on the polymerization system was verified with BA conversion as the evaluation index.
Effect of reactive group types on the properties of core-shell modifiers toughened PA6.

Wear-related microstructures and micrographs linked mechanical properties to wear behavior.
Most research focuses on certain factors while ignoring others because it is nearly impossible to empirically examine all the factors that contribute to the tribological phenomenon.
