Learn what is tensile strength? Its types, units, formula and standard test methods to calculate mechanical properties of various plastics.
yield strength/ultimate tensile strength ratio屈服强度/抗拉强度比值 如有不懂，请追问。 谢谢！
In quasibrittle material such as regular FRC, the ratio of flexural strength (the modulus of rupture) to tensile strength is known to vary between 1 and 3, depending on the details of the reinforcement and the geometry of the specimen. In this paper, the strainhardening behavior observed in ...
Results are presented and discussed from a testing program to study the flexural strength of a rock-like material. In order to investigate the size effects, experiments were performed using specimens of a medium grained size granite. For geometrically similar beams of different sizes, this paper pr...
the equivalent stress σG at the center point of the face plate is 1.62 times greater than its internal center one.In determining the rock tensile strength according to the usual formula,it is recommended that the disc thickness is 0.3 times smaller than the disc diameter.By doing so,the ...
an inherently conservative assumption. This is particularly true for lower-grade materials such H-40, K-55, and N-80 whose UTS/YS ratio is significantly greater than that of higher-grade materials such as P-110 and Q-125. The effect of axial loading on the burst strength is discussed ...

4) specific compression strength 比压强度 1. It found that the compression strain and the permanent compression set values were required to be 20%~25% and under 5% respectively,the specific compression strength was 3. 结果表明,当弹性体的压缩应变在20%/～25%,压缩永久变形率在5%以下时,TPVC...
The RMSE formula is based on Equation (9). 𝑅𝑀𝑆𝐸=1𝑛∑𝑖=1𝑁(𝑦′−𝑦)2−−−−−−−−−−−−− ⎷ RMSE=1n∑i=1Ny′−y2 (9) where 𝑦y, 𝑦′y′ and 𝑁N conveys the measured, predicted, mean values, and the total numbers ...
the tensile strength needs to be obtained using a modified formula, and errors are difficult to avoid [15]. The direct method includes uniaxial tension, triaxial tension, and so on. The two ends of the soil sample are fixed by the fixture, and the tensile strength of the soil sample is ...
