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

Recently, Hill Engineering posted a new case study detailing our research into contour method repeatability. In the case study, we performed contour method measurements on multiple similar specimens belonging to six different specimen types: aluminum T-section, stainless steel plate with dissimilar metal slot-filled weld, stainless steel forging, titanium plate with electron beam slot-filled weld, nickel disk forging, and aluminum plate.
