Two scale analysis of the fatigue of shape memory alloys
Abstract eng: Shape memory alloys (SMAs) are employed in innovative applications experiencing millions of cycles during their lifetime. The existing failure criteria are purely phenomenological based on macroscopic experimental results and ignore their complex microstructure. The proposed paper presents a two-scale fatigue criterion based on the elastic shakedown of the austenitic and martensitic grains of the Dang Van - Papadopoulos class. The underlying assumptions and predictions are discussed on a series of novel experiments and compared with results from literature.
