英文摘要	This Based on the elastic theory of a crack perpendicular to and terminating at biomaterial interface, a generalized expression of the stress intensity factor is provided for a crack in single material and a crack perpendicular to bimaterial interface, finite element methods are used to calculate the stress intensity factors. The influences of the material combination and crack length on the the stress intensity factors were investigated. Results show that when the crack terminates at bimaterial interface, singular order of KIis different from that of single material, and the values of KI increase with increasing E1/E2 and μ1/μ2. © (2014) Trans Tech Publications, Switzerland.
