Prediction of brittle fracture of epoxy-aluminum flanging

Blog Article

This paper presents a fracture mechanical approach for estimation of critical bending load of different types of aluminum-epoxy flanging and comparison with experimental measurements.For this purpose, several opheliasmuse.com designs of the flanges were investigated.The flanges were glued to the epoxy bars and adhesive-epoxy interface was considered as a bi-material notch.Prediction of the failure is based on generalized stress intensity here factor and generalized fracture toughness.
