A Closer Look at Fatigue Surfaces

We’ve previously talked about fracture surfaces created as a result of material fatigue. Through fatigue tests, we are able to create a typical loading cycle on a test specimen to see how the number and magnitude of cycles affects the growth of cracks on the surface. After the test, we can perform fatigue analysis to see how the crack grew over time using a microscope. Continue reading A Closer Look at Fatigue Surfaces
