Plastic Rubber Bend Test

Plastic Rubber Bend Test

Bending strength refers to the maximum stress that a material can withstand when it breaks or reaches a specified bending moment under a bending load. This stress is the maximum normal stress during bending, in MPa (megapascals). It reflects the ability of the material to resist bending and is used to measure the bending performance of the material.

Flexural modulus is also called flexural modulus. is the bending stress ratio to the strain due to bending. The ability of a material to resist bending deformation within its elastic limit. E is the flexural modulus; L, b, d are the supporting span, width and thickness of the specimen, respectively; m is the slope of the straight line segment on the load (P)-deflection (δ) curve, in N/m2 or Pa.

Experimental principle

Bending performance test is mainly used to test the performance of materials when subjected to bending load. Bending tests are often used in production to evaluate the bending strength and plastic deformation of materials, especially for products such as brackets, which are often subjected to bending forces. , flexural strength is known as an important reference index for quality control and application design.
