Abstract Certain dissipative phenomena in long-fibre composites are still quite poorly understood, especially the debonding between the fibre and the matrix. The present study is an attempt to elucidate this phenomenon in SiC Titanium metal-matrix composites. The phenomenon is analysed both experimentally and numerically, both on the scale of the constituents and on the scale of the equivalent homogeneous material. This leads to the identification of a local debonding criterion which helps to determine a global debonding criterion. This approach is made for two cases, without and without consideration of the manufacturing residual stresses.
