Electro-mechanical coupled model for REBCO cylindrical coils

This model was shared by Liangjun Shao, Tsinghua University Haidian District, Beijing (China)

This is a coupled electro-mechanical model for cylindrical REBCO coils. The 
electromagnetic component is based on T-A formulations for the 1-D array of 
REBCO layers in the coil. The mechanical component is based on a classic 
elastic solid model, considering the discrete contact boundary conditions 
between REBCO turns. Multiple General Extrusion units are set to extract the 
Lorenz force and displacement between the electromagnetic and mechanical 
components. The excitation process of this model is defined by the interpolation 
functions, enabling changes to the background field and operational current 
individually.
