purely elastic meaning in English

纯弹性的

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
这些方法各有创新，其特点是计算速度快、收敛性好及精度可靠，计算规模避免了弹塑性随动强化分析的非线性的影响，并使弹塑性问题转化为残余问题和线弹性问题，适用于滚动、滚滑及滑动接触失效分析，从而有效地解决了接触体安定性分析与裂纹萌生寿命预测的实际问题，也是本文对表面强化接触失效的安定分析成为可能。
