macroscopic fracture meaning in English

宏观裂缝

Experimental study of macroscopic fracture of fine aggregate concrete
细骨料混凝土细观断裂试验研究
After continuous researches on macroscopic fracture theories and microscopic fracture theories , characterization parameters of the material fracture toughness have been defined , and the microscopic fracture theories applied in 3d braided cmc also have been proposed . enough numerical simulations have been conducted , and also comparison with the theories has been done
经过对试验的反复推敲和论证，本文从宏观断裂理论和细观断裂理论的角度，确定了三维编织c sic复合材料(三维编织cmc )断裂韧性的表征参量，发展了能够在该材料中应用的细观断裂理论。
