Ferromagnetic shape memory alloy (FSMA) is a new class of functional material. In addition to the general behaviors of traditional temperature-controlled and stress-controlled'shape memory, FSMA can produce large strains under an external application in moderate magnetic fields. This ability makes FSMA suitable for a wide range of applications. This paper reviews the research on mechanical behaviors of FSMA. It focuses on the study of the mechanical behavior, and also includes the topic of the application of the materials. It summarizes the effects of the crystal component, the magnetic field, the stress, and the temperature on the mechanical behavior of the material. It also summarizes the developments of a constitutive model for ferromagnetic shape memory alloy.
