A　hybrid　method　is　established　by　combining　photoelastic　experiment　and　finite　element　analysis.　The　method　is　used　to　evaluate　contact　stress　distribution　on　dry　friction　interfaces,　such　as　the　contact　interfaces　between　shrouds　of　fan　blades　and　turbine　blades.　The　photoelastic　stress　frozen　experiment　method　is　used　to　decide　the　displacement　boundary　conditions　of　numerical　calculation.　Higher　accuracy　and　efficiency　of　solving　problems　are　improved　by　the　method.　Technical　difficulty　and　high　cost　of　experiment　are　also　avoided　by　the　method.　Good　agreement　of　the　stress　distribution　by　using　the　hybrid　method　and　experiment　is　obtained.
