ROTATING BEAM FATIGUE TESTER

About the Rotating Beam Fatigue Tester (RBFT)

Rotating beam fatigue testing machine facilitates testing of materials for the generation of S-N curve from which endurance limit can be determined.

Load is applied using dead weights. The sample is made to rotate, and each revolution corresponds to one cycle of stress (S). Motor stops when specimen fails. Number of rotations (N) to failure is recorded. Tests can be conducted over a wide range of loads.
