	1	Impact Failure of Flattened Brazilian Disc with Cracks——Process and Mechanism显示文摘Split Hopkinson pressure bar(SHPB)has been used to study the dynamic failure pattern of flattened mortar Brazilian disc under impact load.Each disc contains several prefabricated cracks paralleled to each other.Dynamic FEM has also been adopted to simulate such failure behavior.The mechanism of crack initiation,propagation and cut-through have been scrutinized with both experimental and numerical approaches.Influence of the number of the prefabricated cracks on the specimen strength and acoustic emission(AE)performance can be observed and studied.The results show that the strength decreases and AE counts increases,when the number of the prefabricated cracks increases.	张亚芳刘浩 YIN Guoqi OU Chenggui LU Juan HE Juan	2020	Journal of Wuhan University of Technology(Materials Science)2020，35，5：	0
	2	Influence of Intersection Angle of Prefabricated Cracks on Impact Failure of Flattened Brazilian Disc显示文摘Both experimental and numerical approaches were used to study dynamic failure properties and patterns of flattened Brazilian discs,containing two prefabricated cracks intersected at a varying angle.Mechanism of crack initiation,propagation,and cut-through were scrutinized and influences of the intersection angle on specimen strength and acoustic emission performance were also studied.All primary cracks initialize near the middle or the tip points of the upper prefabricated crack,and they continue to develop along the load direction and finally cut through the specimen.The secondary cracks could be observed in directions almost horizontal or parallel to the directions of prefabricated cracks.Furthermore,it is found that stress intensity factor reaches its maximum for specimen with intersection angle of 0 degree.	刘浩张亚芳 YIN Guoqi OU Chenggui LU Juan HUO Yongjie	2021	Journal of Wuhan University of Technology(Materials Science)2021，36，6：	0
