central through crack meaning in Chinese

中心穿透裂纹

This paper , based on the finite element method ( fem ) and utilizing two different means , analyzes the stress and strain field distribution of central through crack tip on a finite flat plate , and calculates the stress intensity factor of the crack tip
摘要基于有限元分析方法，对有限大平板中存在的中心穿透裂纹，分别用不同的方法分析其裂纹尖端应力、应变场分布，计算出裂纹尖端的应力强度因子。
