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.

软硬夹层焊接接头应力状态的数字样机研究

提出了一种软硬夹层焊接接头应力状态的数字原型技术；它以有限元法（FEM）为基础，采用计算机辅助设计（CAD）系统。在NX CAD环境下对中间层进行了数字化样机设计和虚拟实验。计算结果与实际焊接接头断裂的实验数据吻合较好。所提出的数字原型技术可用于软硬夹层焊接接头应力-应变行为的数值模拟。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
