Abstract:

For researching the stress and strain field distribution and the effect of process parameters on forming quality in the precision forming process of mid-thick nut plate, this paper builds the nut plate 3d parts of precise forming finite element entity model in ABAQUS software, and then uses Johnson-cook model to describe the material constitutive relationship and metal material damage and fracture. The ALE adaptive technology has been used to control material large deformation in finite-element analysis of elastic-plastic. Based on this model, this paper analyzes the stress and strain field distribution,average pressure stress distribution and metal material plastic flow rates distribution, and the influence of the process parameters on the forming quality in the forming process.
