Residual stresses in a ring weld specimen after extended creep relaxation
Reheat cracking is a failure mechanism seen in welds fabricated from high temperature creep resistant materials. A new feature test specimen (ring-weld) has been designed to... -
Residual stresses in ultrasonically-peened welded joints
Ultrasonic peening (UP) can improve the fatigue resistance of welded joints by introducing compressive residual stresses at the toe of the welds, and offers significant... -
Intergranular strain development during biaxial loading
The experiment will measure the development of Type II intergranular strains in 316 stainless steel as a function of applied stress for stress states ranging from uniaxial to...
