What Is Flexural Strength

Tensile Strength Vs. Flexural Strength

In the field of materials science and engineering, yield strength and flexural strength are key mechanical properties for evaluating material performance, and they play an important role in safety and reliability in practical applications. The test results of these two properties rely on precise equipment calibration and environmental control.

Nevertheless, yield strength and flexural strength evaluate different types of stress. Yield strength evaluates the ability of a material to resist permanent deformation under tensile stress, while flexural strength evaluates the ability of a material to resist fracture under bending force. Let's take a deeper look at the difference between the two.

First, yield strength is the stress at which a material begins to undergo plastic deformation. In other words, it is the maximum stress that a material can withstand without permanent deformation. In contrast, flexural strength is the ability of a material to resist fracture under bending load. It is the maximum stress that a material can withstand in a bending test.

Secondly, flexural strength is mainly used to evaluate the performance of beams, plates and other structural components under bending loads, and is widely used in construction, machinery, aerospace and other fields. Yield strength is used to evaluate the performance of materials under tensile or compressive loads, and is a key parameter for designing metal structures and mechanical parts.

In terms of testing methods, flexural strength is usually performed through three-point or four-point bending tests, which require specific support and loading devices. Yield strength is usually measured by tensile testing, using a tensile testing machine to apply load and measure the stress-strain curve.

In addition, flexural strength measures the material's resistance to bending stress under bending load, while yield strength measures the material's yield stress under tensile or compressive load. Flexural strength mainly examines the material's elastic and plastic deformation capabilities under bending force, while yield strength mainly examines the material's characteristics of starting to deform plastically under tensile or compressive force.

In summary, yield strength and flexural strength are key indicators for evaluating the performance of materials under different stress conditions. For more details, please click the link below to read the full article.
