Biegeprüfmaschinen

Biegeprüfmaschinen, also known as bending testing machines, are instruments used to determine the bending properties of materials. These machines apply a controlled bending force to a specimen until it fractures or reaches a predetermined deflection. The primary purpose of these tests is to measure a material's resistance to bending, its flexibility, and its potential for failure under such stress.

The operation of a biegeprüfmaschine typically involves securing a sample of the material between two supports. A force is then applied to the center of the specimen, or at another specified point, by a loading nose or roller. The rate at which the force is applied, the distance between the supports (span), and the size and shape of the specimen are all critical parameters that are carefully controlled and documented during the test.

Data collected from a biegeprüfmaschine includes the maximum load the specimen can withstand before breaking, the deflection at various load points, and the bending stress and strain. These results are crucial for quality control in manufacturing, material research and development, and for ensuring that products meet design specifications and safety standards. Different types of biegeprüfmaschinen exist, ranging from simple manual devices to sophisticated computer-controlled universal testing machines capable of performing a variety of mechanical tests, including bending.
