[Joining process]Multi-body forming process
Multi-body plastic deformation problems are hot issues in metal forming simulation. AFDEX started to be applied for several multi-body forming processes since last year. AFDEX V19 has experienced more complicated and actual processes than before. Fig. shows elastoplastic FE predictions of a forming process for assembling three parts. The comparison between 2D results and 3D…

Dieless forming is one of the special forming processes in terms of die or tool motion. Most previous research works employed shell or plate elements. However, the tool-material contact area is so small that pure stretching assumption cannot be applied to the dieless forming process. Therefore, solid element approach has some strong points because local…

An improved special function for the carburizing process will be released in March 2018. For this analysis, the remeshing technology which generates a dense surface mesh has been greatly improved. Fig. is a typical application. Fig. Prediction of carburizing process

Residual stress after self-piercing riveting
The residual stress after self-piercing riveting was predicted using two-dimensional multi-body elastoplastic finite element analysis function. In this representation, the technique of refining the mesh locally near the tip of the rivet as well remeshing was carried out.

Process Validation Forming load accuracy A detailed view of the axisymmetric FE analysis of the riveting process is presented above. The process consisted of two 2024-T3 Al alloy sheets which had to be joined using a 2117-T4 Al alloy countersunk type rivet. The results obtained using AFDEX are compared with experiments as well as a…

Elastoplastic analysis of aircraft fittings and tubes
A two-dimensional multi-body elastoplastic finite element analysis function was applied to a kind of necking process for connecting a high-pressure tube and a fitting of an aircraft. Residual stress due to springback and maximum separation resistance were predicted. 2D 3D
