This is an issue in all injection molded parts and the fact is, we cannot mold even the simplest plastic part without some
residual stress. This
residual stress should be evaluated during design, molding, fixturing and part performance.
Due to the highly concentrated instantaneous heat input,
residual stress is inevitably generated during and after welding.
Influence of customised cutting-edge geometries on the workpiece
residual stress in hard turning
Exploring internal and
residual stress in materials, 46 papers cover diffraction methods; mechanical relaxation methods; acoustic and electromagnetic methods; composites, nanostructures, and microstructures; films, coatings, and oxides; cold working and machining; heat treatments and phase transformations; welding, fatigue, and fracture; and stresses in additive manufacturing.
In the view of several well-known classification societies the utilization of laser cladding technology as a repair method for crankshafts, especially in highly stressed zones such as fillets and bearing surfaces is not acceptable due to a high risk that the heat-affected zone could produce excessive hardness resulting in detrimental
residual stress. The authors of the current work believe that such a view is based upon purely precautionary measures due to the thermomechanical nature of the process, the use of which indeed carries the risk of detrimental
residual stress formation, however no quantifiable data is provided as justification.
The transparent conductive oxide films (TCO) had excellent physical and chemical properties, and the coating process parameters have significant influence on the optical, electrical, and structural properties and
residual stress of the transparent conductive oxide films.
This can be an effect of the relatively small
residual stress relaxation, which as suggested in the previous section, might be outweighing the effect of interfacial adhesion.
