Digital Prototyping of the State of Stress in Welded Joints with Soft and Hard Interlayers

Abstract—A technique for digital prototyping of the state of stress in welded joints with soft and hard interlayers is proposed; it is based on the finite element method (FEM) using computer-aided design (CAD) systems. Digital prototyping of interlayers and virtual experiments with them are conducted in the NX CAD environment. The calculated results are found to agree with experimental data on the fracture of real welded joints. The proposed digital prototyping technique can be used for numerical modeling of the stress–strain behavior of welded joints with soft and hard interlayers.
