Fatigue tests simulate the repeated stretching, compression, bending, torsion, and flexing that automotive components experience under real operating conditions, and are used to evaluate the service life of the components.
| Project Overview
Fatigue is the primary mode of failure in automotive components. During actual use, due to continuous variations in load and speed, these components are subjected to cyclic alternating stresses until failure occurs. This phenomenon is known as fatigue failure, and the mileage or number of cycles at which failure occurs is referred to as fatigue life.
| Test Objective
Fatigue tests simulate the repeated stretching, compression, bending, torsion, and flexing that automotive components experience under real operating conditions, and are used to evaluate the service life of the components.
