Thermo-Mechanical Analysis in W/Cu-Alloy Joints with Different Interlayer Thickness
Thermo-mechanical analysis for W/Cu-alloy joints with different interlayer thickness of OFHC-Cu was carried out by FEM calculation. The result indicated that the compliant OFHC-Cu can significantly reduce the magnitude and concentration of stress and plastic strain, but a weak influence on the temperature distribution. A comparison was made on the residual stress and plastic strain between the fabrication and operation conditions. It was found that the optimum thickness of OFHC-Cu is 1.0 mm in current analysis conditions.
