J-integral　of　nonlinear　fracture　for　the　colloid　soft　material　is　calculated　by　the　finite　element　method　in　this　paper.　The　J-integral　is　based　on　the　concept　of　conservation　of　energy,　hardly　depending　on　the　crack-tip　stress　singularity.　Therefore,　the　fracture　of　colloidal　soft　material　could　be　characterized　by　the　J-integral.　In　this　paper,　a　limited　area　near　the　crack　tip　replacing　the　integral　loop　is　used　to　calculate　J-integral　value.　J-integral　within　one　unit　is　approximated　by　summation　of　the　formulas　related　with　gauss　points.　Such　repeatedly,　J-integral　corresponding　to　integral　path　is　calculated.　Effect　of　different　loading　conditions　and　crack　lengths　on　J-integral　of　PVA-H　nonlinear　fracture　mainly　is　emphasized.　This　study　shows　that　the　J-integral　can　effectively　characterize　the　nonlinear　fracture　of　colloidal　soft　material.　Copyright　©　(2013)　by　International　Conference　on　Fracture.
