From a shape memory alloys model implementation to a composite behavior
چکیده انگلیسی
To obtain an unified treatment of the phase transformation materials pseudoelasticity, a model based on the two independent normal dissipative processes assumption has been developed, one for forward transformation and the other one for reverse transformation. Within the context of building a numerical tool for the optimal design of adaptive structures embedding shape memory alloys (sma), the use of these materials as command components needs the implementation of a specific homogenization method into a structural computation to take into account anelastic constituents. The transformation field analysis is used to predict the pseudoelastic behavior of shape memory alloys reinforced composite materials. The sma composite behavior evaluated by this approach was compared to the response using a two-level micromechanical theory developed by Lu. His prediction considers an inactive elastomeric matrix and volume concentration effects of sma fibers periodically aligned are examined. Both results point to the advantage of using fibrous composites for actuators or sensors under a tensile loading.
