Abstract:The method of AS wire by Castex is an advanced technology, but the corresponding study is incomplete and rough. Dividing the whole process into two stages: Castex stage and bonding stage, the analytic formulae of Castex force of AS wire with any wrapping angle in the three deformation zones of bonding stage using slab method is developed and verified by the measured results gotten from the experiments made on the multi-function Castex machine. The comparison shows that the error is around 15%.
Key words: Castex AS wire Castex force slab method zone
