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(chuàng)新,其特點(diǎn)是計(jì)算速度快、收斂性好及精度可靠,計(jì)算規(guī)模避免了彈塑性隨動(dòng)強(qiáng)化分析的非線(xiàn)性的影響,并使彈塑性問(wèn)題轉(zhuǎn)化為殘余問(wèn)題和線(xiàn)彈性問(wèn)題,適用于滾動(dòng)、滾滑及滑動(dòng)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(yù)測(cè)的實(shí)際問(wèn)題,也是本文對(duì)表面強(qiáng)化接觸失效的安定分析成為可能。
