The bonding course of double partial transient liquid phase in Si3N4 ceramic was firstly simulated by using the method of thermal elastic-plastic finite element analysis and transient thermal structure. Then resident stress distribution of joints and the influence of interlayers were investigated.
In this research work, the thermal elastic-plastic method is used to analyze the dynamic thermal stress in the stress-frame specimen during its solidification and cooling process.
The obtained transient temperature field can represent the basic characteristics of the real welding process and can be used as the foundation of thermal elastic-plastic analysis.
A two-dimensional model to simulate the strain and stress of weld metal during solidification is established with non-linear thermal elastic-plastic FEM for SUS 310 S austenitic weld.
According to the PD6493: 1991 level 1 approach, the influence of welding residual stress on the CTOD design curve in welded joints with central transverse cracks is studied by a thermal elasto-plastic finite element method.
A thermal elastic-plastic finite element model (FEM) is utilized to calculate the residual stress distribution across the cantilever cross-section and to determine the beam tip deflection following heat treatment.
The results confirm the ability of the developed thermal elastic-plastic finite element contact model to predict the residual stress distributions within micro-fabricated cantilever structures with high accuracy.
This paper presents the characteristics of residual stresses in welds of similar and dissimilar steel weldments by carrying out three-dimensional (3-D) thermal elastic-plastic finite element (FE) analysis.
The three-dimensional (3-D) thermal elastic-plastic analysis of a cooling roll has also been carried out, to obtain roll stress and plastic strain distributions, with the commercial finite-element analysis package of ANSYS.
Second, the thermo-elasto-plastic finite element method is used for the welding stress calculation, in which the phase transformation is considered by the "equivalent linear expansion coefficient method".
Thermo-elasto-plastic constitutive equations including creep and iterative finite element formulation during continuous casting with phase change have also been presented.
We use the thermo-elasto-plastic constitutive equation of a particle-reinforced composite, taking into consideration temperature changes and damage as well as the reinforcing effect of particles.
During each fatigue cycle, the temperature oscillations, which were due to the thermal-elastic-plastic effects, were observed and related to stress-strain analyses.
