Evolution of Crack Tip Plastic Zones of Specimen Size with Yield Stress

Journal Name:

Publication Year:

Abstract (2. Language): 
With the face of crack, there exists a plastic zone which affects the evolution of the aforesaid the crack. The opening of this crack or the spacing is in direct relationship with this zone. Irwin proposed a simple model by applying plane constraints to the point of the crack. In the same way for Rice who has her concept establishes. We will see the influence of the spacing criticizes of a crack of an alloy (Al-Cu) used in aeronautics on tenacity and the strength parameters in bottom of crack, let us consider two international standards of them Russian and English. We complete our work by simulation by finite elements (FE) by Castem2001.
