In bridges, building structures and other engineering projects, pure bending deformation is very common. In this experiment, strain and deflection is measured to analyze the basic properties of structures and materials. If the equipment is slightly modified, you can perform the experiment of bar stability, concentric tension and compression, eccentric tension and compression and so on. The experiment enables students to learn the dialectical relationship between theory and practice, but also enhances their practical abilities.
System Composition and Principle
This product is designed with enclosed steel frame and cast composition with careful surface treatment. It is a durable fastening structure. For each type of experiment, the product equips with specimens and surface treatment samples and accessories. The system consists of Base, Pure Bending Beam, Sensor, Strain Instrument, Strain Gage, wires and so on. The strain instrument can connect to a computer and the data can be processed with our software.
The basic principle of this strain-stress electrical measurement method: measuring a specimen's surface strain with strain gage, then the specimen's surface stress state is determined according to the strain-stress relationship. The strain-stress electrical measurement method is not only used to validate the basic theory of mechanics of materials, to measure the mechanical properties of materials, but also is a major engineering testing means for solving engineering problems. It provides a good experimental basis for scientific research.
