Abstract: High tensile weld residual stress is an important factor contributing to stress corrosion cracking (SCC). Ultrasonic impact treatment (UIT) can produce compressive stresses on the surface of ...

Abstract: Ultrasonic impact treatment (UIT) can be used to create a thin nanostructured surface layer that plays a significant role in enhancing the overall strength, fatigue life, and corrosion resistance ...

Abstract: A nonlinear elastic-plastic finite element method is established to predict the residual compressive stress distribution induced by laser peening (LP) in AISI 304 stainless steel. The dynamic ...

Abstract: Continuum damage theory has proven to be an effective tool in creep damage simulation. In order to establish some mechanical principles for life extension of components at elevated temperature, ...

Abstract: Creep deformation localization is a common occurrence generally found in high temperature components, typically at weldments and geometrical discontinuities. The deformation in a small region cannot ...
