A This relationship characterizes the fracture resistance of structural materials by defining a critical strain energy release rate ( G c ) at the critical load ( P c ) when fracture occurs in a specimen with a known compliance function ( dC / dA ). In LEFM, it is assumed that the part contains a crack or other...
