摘要: Shape memory alloys are well recognized functional and smart materials, which have been exploited to develop intelligent structures devices in many fields. Of particular importance is its exciting application the field of biomechanical engineering. In addition, further potential applications shape being investigated, such as alloys-based composites. Recent experimental research indicates that alloy nickeltitanium (NiTi) superior stainless steel against wear could be applied tribological It believed super resistance mainly due recovery superelastic deformation. Our recent study rate very sensitive maximum contact pressure. present study, involves applying Hertz theory finite element method, behavior investigated through analyzing contrast existing explanation major contribution superelasticity, our investigation directly linked low Young's modulus alloy, transformation stress large strain, result pressure therefore rate. Additionally, high plastic yield strength transformed martensite NiTi also enhances resistance.
