What is a bending testing machine
In fields such as industrial manufacturing, materials science, and construction engineering, bending testing machines are commonly used testing equipment to evaluate the flexural strength, elastic modulus, and fracture properties of materials. This article will introduce in detail the definition, working principle, application fields of bending testing machines, and recent hot topics related to material testing.
1. Definition and working principle of bending testing machine

A bend testing machine is a device that measures the mechanical properties of a material by applying force to bend it. It usually consists of loading system, control system and data acquisition system. Here’s how it works at its core:
| components | Function |
| Load system | Bending force applied via hydraulic or motor drive |
| control system | Adjust loading speed and force |
| data acquisition system | Record force, displacement and deformation data during bending |
2. Application fields of bending testing machine
Bending testing machines are widely used in many industries. The following are the main application scenarios:
| Industry | Application examples |
| building materials | Test the bending resistance of concrete and steel bars |
| metal processing | Evaluate the bending strength and toughness of sheet metal |
| Plastics and composites | Determine the flexural modulus of plastic pipes or fiberglass |
| automobile manufacturing | Verify the bending resistance of body materials |
3. The relationship between recent hot topics and bending testing machines
In the past 10 days, many hotly discussed topics on the Internet are closely related to material testing and bending testing machines:
| Popular events | Related content |
