The presence of fibrous tissue,so that the mechanical properties of metal materials have obvious anisotropy,the use of mechanical parts and processing technology will have a significant impact.Correct understanding and use of the fiber direction of the material is one of the important issues that need to be studied in material processing.In order to explore how the fiber direction affects the deformation degree of metal sheet material,A geometrical analysis model of the deformation of sheet material is established,The analysis shows that the deformation degree is positively correlated with the width and Angle of the deformation area,negatively correlated with the length of the deformation area,and the width is more sensitive to the deformation effect;To explore how the fiber direction affects the degree of distortion and deformation of sheet metal,Referring to the existing research and related material performance test standards,A set of strip specimens with fixed length of deformation zone is designed,Two widths and three thicknesses were selected on the Q235 steel bar,and the fibers were distributed along the longitudinal,transverse and thick direction,The direct distortion test is completed by using special test equipment and the relevant quantitative data are obtained;The test results show that the sample is easy to be destabilized due to its small thickness.Fiber direction along the longitudinal distribution of the maximum degree of distortion deformation,transverse,thickness is the worst?... |
