摘要：
The interfacial quality of shape memory alloy (SMA) composites was experimentally evaluated by differential scanning calorimetry, and quantitatively calculated using a combination of Sittner's model and a composite cylinder model. Results have shown that the damage level of the interface in a heating process can be quantitatively evaluated by measuring the transformation enthalpy of the subsequent heating cycle and comparing it with the S-shaped enthalpy kinetic curve. A combination of Sittner's model and a composite cylinder model is capable of calculating both the thermal behavior and the triaxial stress state of SMA composites.
