Vibration causes fruits mechanical and physical damage during transportation and affects the fruits storage characteristics and sales.
Therefore, study on the vibration load caused injury factors have very important value [1].
The initial mechanical properties and damage fruit and vegetable researches focus on agricultural products, for agricultural products post-harvest storage and sorting, grading etc..
The vibration acceleration is one of the important factors in injury, so layer numbers are an important factor.
These two layer numbers are the damage factors of Huangguan pear.

The fatigue strength is affected by many factors such as surface roughness, residual stresses, porosity and inclusion.

Introduction When a soil specimen is sheared in an axisymmetric triaxial compression test, its mechanical and material behaviors are affected by multiple factors, i.e., material properties of the soil, confining pressures, initial void ratios, and etc.
However, it would take huge amount of time and efforts to investigate these factors if using laboratory tests.
For soils, especially sands and gravels, the size of particles affects not only mechanical behaviors (i.e., stress-strain response) but also material behaviors (i.e., permeability, void ratio, tortuosity, etc.).
The initial moduli for all three specimens are almost the same, which proves that they were not affected by particle sizes.
For real soils, particle breakage will affect the results substantially.

Surface preparation is potentially important to the mechanical and biomedical properties of NiTi shape memory alloys.
In recent years, surface preparation has attracted considerable attention due to its potentially important effect on properties of NiTi alloys [4-6].
There are many factors that affect fatigue life of NiTi wire.
The smoother surface has less slag, burrs, scratches or heat affected zones, and therefore less stress concentrations under exogenous action.
In addition, the hydrogen brittleness, caused by the hydrogen atoms absorbed in the course of the surface treatment, will severely deteriorate the mechanical properties.

At the present time, mechanical properties are usually tested through rod-shape specimen, but the mechanical properties of plate-shape specimen of P/M superalloy are hardly studied.

Heat affected zone.
It can be seen that there are a large number of inclusions, which was one of the important factors leading to cracks.
Impurities in the welding seam are one of factors causing low strength of welded joint, as shown in Figure 6.

Water in liquid and gaseous form is the main factor which significantly affects degradation processes in the wood.
This article presents results of the experimental study that deals with the mechanical properties of bonded joints in the wood treated by silicones.
Even some other studies [8] show that the adhesive joints in the modified wood may show different mechanical properties depending on the type of adhesive used or environmental effects [9].
The depth of the intersection, respectively the depth affected by modification depends on several factors, e.g. on species, steep time, etc.

The effects of technical conditions on the mechanical properties of WPC were investigated.
In the process of WPC production, the properties of the final product is not only affected by plant fiber types [1], modified method [2], matrix type and interface properties [3] and other factors, but also directly affected by the molding process [4].
In the mixing and molding process, the factors affecting the product quality are usually includes mixing temperature, mixing time, molding pressure, molding temperature, molding time and etc [5-6].
The effect of mixing time on the mechanical properties of ONPF/rPP composites was depicted in Fig.3 and Fig.4.
Further increase in the molding pressure resulted in a decrease in mechanical properties.

Using Bergmann's loading factors, stress calculations were conducted for an 80 kg individual.
Generally, the law of mixtures and various reaction models are used to describe the behavior of composite materials and predict their mechanical properties.
The mechanical properties are determined through specific mathematical relationships that incorporate the volume fractions and properties of both the reinforcing fibers and the matrix material.
The analysis encompassed the determination of key mechanical properties, including Young’s modulus, shear modulus, Poisson’s ratio, density, ultimate tensile strength, and fatigue life under cyclic loading conditions by incorporating Bergmann’s physiological loading factors and applying the Goodman fatigue criterion, the simulations provided a detailed assessment of how varying fiber volume fractions affect the structural integrity and long term durability of the composite, with direct relevance to orthopedic implant performance.
Mechanical and physical properties of Carbon/Silicon composite The study of mechanical and physical properties of the Carbon/Silicon composite shows that increasing the fiber volume fraction improves stiffness, strength, and shear resistance while slightly increasing density.
