Discussion and Analysis on the Progress of Fatigue Destruction and the Geometric Characteristics of Destruction Surfaces
[Reproduction of Private Spring Preparatory School Lecture 15] Explanation of ductile fracture and brittle fracture! Also explains the smooth and rough surfaces of fatigue fracture.
I am studying the "fatigue strength of spring materials," and today, let's explore the characteristics of the fracture surface that occurs due to fatigue failure, how it forms, and how it differs from other fracture surfaces, specifically the features of fatigue fracture surfaces. When a material fails under static loading, it can either break after undergoing significant plastic deformation or fail with little to no plastic deformation. The former is referred to as ductile fracture, as seen in the fracture of mild steel during tensile testing, while the latter is known as brittle fracture, observed in the fracture of hardened high-carbon steel or gray cast iron during tensile testing. *For detailed content of the article, please refer to the PDF.

Company information
Accurate offers a wide range of products including compression springs, extension springs, torsion springs, wire forming, battery springs, and flat springs in the Ultra Spring (Accurate Original standard spring) series, as well as custom-made items and both wire and sheet materials. We are capable of manufacturing and selling these products. Additionally, we have permanent showrooms for springs in Akihabara, Nagoya, and Kyoto. We maintain a constant stock of catalog items, including Ultra Springs, enabling immediate delivery. Currently, Ultra Springs has approximately 3,000 different items, all with manufacturing lot numbers for traceability, and we promote the industry's first two-point load management and no discontinued items, striving for quality and supply stability to expand globally. Our free spring selection and design software, "Select Spring-kun," allows for easy selection of Ultra Springs, spring design, lifespan calculations, estimates, and delivery date confirmations. The Accurate Tangless Insert reduces the work time of conventional products (Heli-Coil) to one-sixth, and is a NAS-certified revolutionary product that achieves cost reduction for screw hole operations in aluminum cutting and resin materials, particularly in the aerospace and aviation industries, as well as high-speed rail and semiconductor manufacturing equipment, and medical devices.
