TiNi Alloy Lattice Structures with Negative Poisson’s Ratio: Computer Simulation and Experimental Results

One of the issues that modern implants face is their high stiffness, coupled with a positive Poisson’s ratio along implant. This creates certain problems bone inflammation and implant detachment. A possible solution to these TiNi alloy lattice structure low stiffness negative ratio. paper presents results simulation, fabrication by SLM technique, study structures ratio, which can help solve said problems. The studies involve determination mechanical characteristics, transformation temperatures, potential for superelasticity effect structure. characteristics obtained at initial simulation were partially confirmed in course works. Moreover, possibility fabricating (about −0.00323) Young’s modulus values (0.818 GPa) was technique.
