Based on the catastrophic characters of the whole strain energy in truss structural instability, the relationship between the whole strain energy and the stress rate in the link element was educed, and the stress rate criterion for judging the instability of truss structures was built up through analyzing the changing law of stress rate
基於桿系結構發生動力失穩時的總應變能突變特徵，推導總應變能同桿單元應力變化率之間的關系，並分析應力變化率的變化規律，建立了判定系結構動力失穩的應力變化率準則。
