In the present study, detailed welding distortion of bead welded plates under temporary tacking state and released was predicted by thermal elastic-plastic finite element model (FEM) also measured digital image correlation (DIC) method. It found that residual angular can be reduced to about 50–60% tacking, while transverse shrinkage longitudinal are less affected. Further, with different ratios length weld for various dimensions quantitatively investigated FEM. The inherent deformations...
Hot forming is an effective approach for improving the formability of ultrathin metal sheets, such as those made stainless steel and pure titanium. However, increased friction coefficient between tool high-temperature sheet negatively affects material flow during hot forming, potentially resulting in severe local thinning or even cracking. This study explores frictional behavior 0.1 mm thick ferritic (FSS) commercially titanium (CP-Ti) sheets at elevated temperatures. A testing apparatus was...
Surfacing on the surface of thin metal bending plates will cause significant deformation, and current numerical simulation experimental methods cannot fully truly reflect deformation state plate. In this paper, a non-contact detection method based three-dimensional (3D) thermal digital image correlation (DIC) is proposed. The proposed can be used for 3D full-field dynamic measurement plate surfaces. addition, evolution law in-plane out-of-plane during surfacing welding cooling was studied....

The water sensitivity and structural characteristics of collapsible loess are two typical factors that significantly influence its mechanical behaviors. This paper presents a simple practical elastic-plastic model based on the modified Cam-Clay to well capture essential behavior unsaturated intact loess. employs deviator stress spheric as variables, with content serving moisture variable. critical state surface can be determined by utilizing shear strength parameters soil under axisymmetric...
Heat input is a crucial parameter in the process of welding thin plates. It has direct impact on quality weld and degree deformation caused during welding. This study investigates heat bending plate its zone using thermoelastic–plastic finite element method. The accuracy model ascertained non-contact inspection method utilizing digital image correlation technology. patterns plates with radius 500 mm were analyzed at various inputs ranging from 173 J/mm to 435 J/mm. results indicate that...
