The direct analysis method has more efficient than the line programming for the shakedown analysis of contact surface layer, therefore, the mentality of shakedown analysis of contact surface layer was introduced based on the direct analysis method as follows : first, the direct method for shakedown analysis was presented and its application to a two - dimensional rolling / sliding contact problem was demonstrated. the direct method consists of operator split technique, which transforms the elastic - plastic problem into a purely elastic problem and a residual problem with prescribed eigenstrains, and an incremental projection method to determine the eigenstrain
這些方法各有創新，其特點是計算速度快、收斂性好及精度可靠，計算規模避免了彈塑性隨動強化分析的非線性的影響，並使彈塑性問題轉化為殘余問題和線彈性問題，適用於滾動、滾滑及滑動接觸失效分析，從而有效地解決了接觸體安定性分析與裂紋萌生壽命預測的實際問題，也是本文對表面強化接觸失效的安定分析成為可能。
