In my May 2020 CW column, I introduced a new test method for measuring the fracture toughness within the facesheet-to-core interface region of sandwich composites. This proposed test method, referred ...

Even today, the failure of engineering components and structures as a result of fracture, fatigue, creep and corrosion is not an uncommon event. With a greater understanding of these failure ...

Mechanical parts are more frequently subjected to cyclic loads than solely static loads. Fatigue issues are commonly observed in turbine blades, aerospace components, locomotive systems, large ...

EPRI (Electric Power Research Institute) reports that 7FA gas turbines have a rotor life of about 144,000 hours, or 5,000 starts. The primary life-limiting factor is high cycle fatigue cracks ...

Inside the massive testing hangars across Seattle and Everett, the world's biggest jetliners are turned into mechanical lab rats. Hydraulic actuators yank their wings skyward, compressors simulate ...
