medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .it is achievable by shape memory effect. for this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. then shape memory effect was ind...

In this paper, the effect of thermomechanical loading on the behavior of deflection-based harvested energies from a shape memory polymer system is experimentally investigated. Samples are created with honeycomb cells from poly-lactic acid using additive manufacturing techniques. The shape memory effect in shape recovery and force recovery paths are studied under thermomechanical tests in bendin...

in this research, shape memory effect of polycaprolactone based polyurethane/poly(vinyl chloride) blends in which the pvc weight percentage are 10, 20, 30, 40, 60 and 80 were studied using dma apparatus. the compatibility, tension and dynamic-mechanical properties of these blends have been studied by the authors and this paper specifically deals with the tests results of shape memory effect. th...

A central problem in computer vision is to detect, delineate (segment) and recognize objects in an image. One reason why this is diicult is that very little information speciic to given types of objects is used during segmentation. Making use of information about an object's shape, for example, should facilitate and improve the segmentation of that object. This paper introduces a 2D discrete gr...

In this paper, the shape memory, mechanical and Izod impact properties of a new shape memory nanocomposite based on thermoplastic polyurethane (TPU), acrylonitrile butadiene styrene (ABS) and alumina nanoparticles were investigated. The morphological results showed that the presence of 1% alumina nanoparticles made a reduction in diameter of ABS domains and caused a uniform distribution of the ...
