摘要: | A new computational procedure for including welding-induced residual stresses and distortions from weld simulations in the SYSWELD software code in structural Finite Element Analysis (FEA) simulations performed in the Abaqus FEA code is presented. The translation of these results is accomplished using a newly developed Python script. Full details of extracting the results from SYSWELD, translating these results using the newly developed Python script, and including the results in Abaqus are provided through an illustrative example analysis of a butt-welded aluminum plate. The development of this capability is motivated by the Navys increased use of lightweight aluminum structures where including the effects of welding in structural components can be critical to understanding structural response. The integration of SYSWELD and Abaqus enables Code 60 engineers to increase the efficiency of design through the integrated computational materials engineering (ICME) paradigm, which emphasizes the use of computational tools to understand design performance, while minimizing the amount of traditional physical testing. This project is part of a program entitled Integrated Computational Design and Analysis Aluminum Ship Materials and Structural Performance (Al ICDA). |
