... of preexisting tracks on melt pool formation, powder catchment, geometry evolution, dilution, residual stress, and defect generation. CPM 9V steel powder was deposited on the H13 tool steel substrate for validating the model. The deposition height is found to be a function of the track sequence but reaches...

...Sébastien Rouquette; Camille Cambon; Issam Bendaoud; Sandra Cabeza; Fabien Soulié Residual stresses have been characterized in four Wire Arc Additive Manufacturing specimens with neutron diffraction technique. First, two methods are investigated for obtaining the reference diffracted angle θ 0...

... forming (SPIF) leading to the desired geometrical deformation. Machining a material block to produce thin structure results in unwanted residual stresses in the workpiece, which hinders the part’s formability during SPIF. In the current research, stress-relieve annealing of aluminum alloy (Al 6061...

...Maziar Toursangsaraki; Huamiao Wang; Yongxiang Hu; Dhandapanik Karthik This study aims to model the effects of multiple laser peening (LP) on the mechanical properties of AA2024-T351 by including the material microstructure and residual stresses using the crystal plasticity finite element method...

...Mohammad I. Hatamleh; Jagannathan Mahadevan; Arif Malik; Dong Qian; Radovan Kovacevic Residual stress (RS) is a major processing issue for selective laser melting (SLM) of metal alloys. Postprocessing by way of heat treatment or hot isostatic pressing is usually required for acceptable mechanical...

Yi Injection molding of plastic optical lenses prevails over many other techniques in both efficiency and cost; however, polymer shrinkage during cooling, high level of uneven residual stresses, and refractive...

...Sagar H. Nikam; N. K. Jain Prediction of residual stresses induced by any additive layer manufacturing process greatly helps in preventing thermal cracking and distortion formed in the substrate and deposition material. This paper presents the development of a model for the prediction of residual...

...R. W. McCune; A. Murphy; M. Price; J. Butterfield The ability to accurately predict residual stresses and resultant distortions is a key product from process assembly simulations. Assembly processes necessarily consider large structural components potentially making simulations computationally...

...Jani Kenda; Franci Pusavec; Janez Kopac In machining processes, surface integrity is a major quality-related performance output. In the case of difficult-to-cut materials, this frequently relates to residual stresses induced in the machined surface and subsurface. As cryogenic machining presents...

...V. Kobelev The excessive stresses during the coiling of helical springs could lead to breakage of the rod. Moreover, the high level of residual stress in the formed helical spring reduces considerably its fatigue life. For the practical estimation of residual and coiling stresses in the helical...
