To find them, two typical high-strength steels with a wide range of tensile strength including AISI 4340 steel (tensile strengths ranged from 1300 MP to 2400 MPa) under push-pull load and SCM 435 steel (tensile strengths ranged from 990 MPa to 1900 MPa) under rotating-bending load were chosen to investigate the parameters of S-N curves. The maximum force that was applied is then divided by the cross-sectional area to obtain the maximum stress it was subjected to. This maximum stress is the value of ultimate tensile strength. The SI unit of ultimate tensile strength is N/m 2 or Pascal with large numbers being expressed in megapascals. Examples for Material Tensile Strength
Qualitative and quantitative differences were observed between the three different techniques used to layer the meniscus. . From a mechanical point of view, the negligible effect of failure mode on DB tensile strength is a perplexing result. One possible explanation is that a disproportionally higher number of stronger specimens fail at the .
Objectives: The aim of this study was to explore the potential of boosted tree (BT) to develop a correlation model between active pharmaceutical ingredient (API) characteristics and a tensile strength (TS) of tablets as critical quality attributes.

Stereological techniques based on countings of points and intersections were used to quantitatively characterize the anatomy of each species. Modulus of elasticity and proportional limit stress values were found to be more .

The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.S-N curves of AISI 4340 and SCM 435 steels were determined according to the qualifications and systematically investigated by Basquin relation. The change of parameters (fatigue strength coefficients and exponents) of these S-N curves with increasing tensile strength was analyzed and summarized. For the steels with the same type of S-N curves, as tensile strength .

Quantitative phase fraction of M/B using EBSD analysis measured M: 40.37% and B: 59.63% for alloy A, and M: 53.03% and B: 46.97% for alloy B.

For SCM 435 steel, similar results can be observed. When tensile strength is in the range from 900 to 1700 MPa, the ratio of surface cracking sites (RSCS, the ratio of the number of failure samples originated from the surface site to the total number of failure samples) equals 100%, namely, all fatigue cracks originate from surface, which implies that the fatigue .
Ultimate Tensile Strength
Hardness and tensile strength are important mechanical properties of materials [1]. The hardness and tensile strength can not only directly reflect the comprehensive mechanical properties of material, but also they are closely related to the friction properties, fatigue resistance, stress corrosion resistance and plastic properties for the key components in service [2], [3], [4].
Consequently, some scholars tried to establish quantitative relationships between tensile properties (faster and more stable) and fracture toughness. . It is found that the tensile strength of 40CrNiMoA steel declines gradually with increasing the tempering temperature.
