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: This paper presents a numerical study of the mechanical properties of a binary mixture of similar prolate ellipsoids of various particle shapes and fines’ contents using the discrete element method. The ratio of the major ...

Abstract: The morphology of fragments produced by grain fragmentation is a cause for great concern in many areas such as rockfill dam and the mining industry. Therefore, there is a need to conduct a quantitative analysis of the ...

Abstract: Environmental issues are often neglected in previous studies on site layout evaluation problems. To address this research gap, a comprehensive evaluation model is developed to evaluate construction site layout planning in ...

Abstract: A set of numerical experiments of simple shear tests of rockfill–structure interfaces were performed using the combined finite- and discrete-element method (FDEM). Each particle was modeled as a polyhedron to represent ...
