Abstract

Damping capacity of metallic materials represents an attractive property for many kinds of applications. Shape memory alloys present besides memory effect and super elasticity a high value of internal friction especially on martensitic transformation temperatures domain. Paying respect for material properties using simulation software nodal von Misses tensions were appreciate at external loadings. Input data used in this study were experimentally determinate using a dynamic mechanical analyzer. The results exhibit differences of behavior, especially values of internal nodal tensions, between metallic materials and in shape memory alloys case between material states given by temperature variation concerning the martensitic transformation range..
