Comparison of Elastic Constant for Borassus flabellifier in the Longitudinal and Perpendicular Direction of Fibres with Frequency

Abstract:

ndia is veritable emporium of medicinal and aromatic trees. It has been estimated those trees occurring in India are commonly useful. Neera natural liquid is useful for different purpose like in bio-medical, chemical industries etc. The study of elastic behaviour of a solid is very important in fundamental and technical research. Solid bodies are not absolutely rigid by the application of suitable forces. We used the composite piezoelectric oscillator technique to calculate elastic behaviour of Borassus Flabellifier wood part from where the natural liquid NEERA collected overnight. Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. Ultrasonic Inspection is a very useful and versatile NDT method to calculate the ultrasonic longitudinal velocity and elastic constant of male and female tree (Borassus Flabellifier) wood part in the longitudinal and perpendicular direction of fibres with frequency at room temperature of 311 K. We have measured the resonant frequencies of the specimens f_s. The specimens were collected from Dhar Dist. (M.P.) India. Characterization of the samples was made by scanning electron microscope (SEM) Model JEOL JSM5400. The resonant frequencies of the specimens were measured by Ultrasonic Interferometer (for solids) dual frequency Mittal Enterprises, New Delhi.
