Development of computer technology for modeling residual welding phenomena

Objectives. The objectives of the work are to demonstrate the possibility of applying computer technology for modeling residual welding phenomena and compare them with the results of analytical calculations for classic welded structures. A software package project for automating the calculation of residual welding phenomena is presented.

Methods. The principles of applying the force-based method for calculating the stress-strain state (SSS) of general-purpose welded structures are demonstrated using the example of beam and shell welded structures. A description of existing approaches for calculating welding phenomena is provided, as well as a software package implementing the force-based method for calculating the SSS of welded structures. Prospects for transitioning to parallel architectures and further development and application of the force-based method are analyzed.

Results. Good convergence of the results of calculating deformations of welded structures in comparison with analytical methods and the possibility of automating the creation of computer models for calculating residual welding phenomena are shown, using the example of a software complex project. Conclusion. The main directions of development and advantages of the technology are highlighted: reduction of labor intensity, CAD integration, optimization of assembly processes, and scalability. Prospects for transitioning to parallel architectures are discussed.
