T-stress evaluation for multiple cracks in FGMs by the numerical manifold method and the interaction integral

[Display omitted] •T-stresses of cracked 2D FGMs are evaluated with numerical manifold method.•Discontinuity and singularity of physical fields around the crack are well captured.•The T-stresses are computed by domain-independent interaction integral.•Our results are in nice agreement with the avail...
