  • Thermography Applied to Cultural Heritage
    Two application studies of indoor and outdoor IR surveys applied to the diagnostic analysis of stone materials constituting Cultural Goods are described in the following. In the frame of a conservation intervention carried out in 2001, certain panels (Hermes Trismegistos, Libyan Sibyl, Delphic
  • Ultrasonic Technique and Device for Residual Stress Measurement

  • The Use Of Engineered Compressive Residual Stresses To Mitigate Stress Corrosion Cracking And Fatigue Failure In 300m Landing Gear Steel (.pdf)
    (SP) is commonly used to improve the fatigue performance of high strength steels, but provides only partial corrosion fatigue benefit, only very shallow damage tolerance, and no significant SCC improvement. Surface treatment with low plasticity burnishing (LPB) has been applied to create
  • How to Manage Stress
    Design engineers with considerable experience in metals may overlook the effect creep can have on the long-term performance of a plastic part, particularly when applications involve high operating temperatures. When a stress is applied over a long time, the observed strain is greater than
