- •
We present the mechanical models of ETFE cushion via flat-patterning method.
- •
The form-developing test of ETFE cushion through flat-patterning was performed.
- •
The forming process was divided into inflating, creep and creep-recovery phases.
- •
Internal pressures, rises, shapes, and stress and strain distributions were obtained.
- •
Elastic deformation, viscoelastic creep, recovery and strengthening were revealed.
