The main research is below : ( 1 ) the influence to intensity and rigid with corner angle ( 60 , 75 and 90 degree ) of crack and the board axes ( 2 ) do a fem stress / strain and crack growth simulation analysis when the corner angle of crack and the board axes is 60 degree ( 3 ) do a intensity resume analysis for the structure which is repaired with a titanium patch in a mechanical way when the corner angle of crack and the board axes is 60 degree through simulation analysis for three failure criterion , we have : ( 1 ) in 60 , damage extend quickly with damage analysis in hashin criterion ; it is slower for analysis in maximum stress or hashin - rotem criterion . ( 2 ) in special term ( physical condition incision , shape or maximum load ) the compression strength of the stiffened plate will decline 45 % ~ 50 % under compression loads
通过采用三个不同损伤判据的数值仿真模拟，得到如下结论： ( 1 )在60时，用hashin判据进行的损伤分析，损伤扩展较快；最大应力及hashin - rotem判据进行的损伤分析，损伤扩展基本相当，且较慢； ( 2 )在所给加筋板的物理条件、切口大小及形状、最大载荷等一定的条件下，该加筋板在压缩载荷作用下，其压缩强度下降了45 50 ； ( 3 )在本文提及到的机械连接修理方法以及载荷条件下，修理后的结构强度恢复能够满足战时要求。
