One interesting feature of Tokamak is support for modelbreakage, where composite objects can break on collision, then creating multiple objects in the simulation.
By processing the original power signal with dispersing autoregressive model AR, the difference between the measured value and the forecasting value of the model is used to judge the tool breakage.
功率原始信号经离散自回归AR模型处理，利用信号的实测值与模型预测值之间的预测偏差来判断刀具的破损。

A new droplet breakage criterion and a modified model of droplet breakage frequency which account for the effect of dispersed phase viscosity on drop deformation and breakage were presented.
