What is Hall-Petch Strengthening? Hall-Petch strengthening is a phenomenon where decreasing the average grain size of a material leads to increased yield strength and hardness. This effect is ...

Automotive, aerospace and defence applications require metallic materials with ultra-high strength. However, in some particular high-loading structural applications, metallic materials shall also have ...

High yield steel embodies exceptional performance under extreme structural loads. Tension, compression, impacts, abrasion and vibration are usual loads applied upon heavy industry components when in ...

Aug. 25 (UPI) --A team of mechanical engineers has developed a super steel called D & P Steel to improve the strength-ductility trade-off. Aerospace, automotive and defense applications need metallic ...

Strength, ductility and toughness are three very important, closely related material properties. The yield and ultimate strengths tell us how much stress a material can withstand, and are often used ...

As fields ranging from health care to robotics increasingly use flexible materials for electronic devices, Northwestern Engineering researchers have developed a thickness-dependent metric that allows ...

Most engineers who deal with bolted joints are familiar with torque tables for SAE-grade bolts, but these are all too often used without regard for the yield strength of internal threads or the bolt’s ...

This file type includes high resolution graphics and schematics when applicable. However, this relationship between stress and strain in a material is linear only when the force applied is within ...
