摘要: Abstract Cracks in stepped and continuously graded material specimens under flexural loading were investigated via finite element analysis. Calculation of mechanical energy release rates propagation angles with crack-opening displacement correlation the local symmetry (KII = 0) criterion, respectively, provided results most efficiently accurately, as compared compliance J-integral approaches other deflection criteria. A routine was developed for automatic crack extension remeshing, enabling simulation incremental propagation. Effects gradient profile geometry on crack-tip stresses path are examined, implications these optimal design components against failure by fast fracture discussed.
