Abstract
Considering the failure due to cracks and peeling from curved surfaces of complex components, we used the tight hammering method to study the internal plastic deformation zones of curved-surface Q235 steel specimens after hammering shock and display relevant information. A Dino-capture microscope and a ZEISS LSM 700 laser scanning microscope were used to obtain and fit the morphologic data of rebounded zones and identify effective boundary points. Data of the boundary points were processed by least squares fitting. After curved-surface specimens of different curvature radii and planar specimens were hammered by the SR5.5 punch head and the plastic zones on the tight curved surfaces were all circularly-shaped at different impact strokes. The hammer traces were symmetrical spatially, indicating the internal plastic zones of the tight curved-surface specimens were approximately spherically-shaped. Deformations of plastic zones at external corners were large in magnitude and small in area, while those at internal corners were small in magnitude and large in area.
