Abstract
In this paper we have calculated the second and third order elastic constants of SWCNTs at room temperature using the interaction potential model. The approach with some modification has been established for the SWNTs nanomaterials. Further the ultrasonic properties have been determined with help of the non-linear elastic constants and other related parameters for characterization. It is observed that tube length dependent thermal conductivity is prominent reason behind the ultrasonic attenuation.
