Abstract

The elastic constants for LiBC using higher order Eulerian strain equation of state accordance with method of augmented plane wave under various temperature and pressure have been explored. In present study, we employed Hama-Suito theory of equation of state. The constants C11, C12, C44 and temperature dependent of bulk modulus have been calculated up to high temperature and low compressions. The relation among pressure, volume and temperature have also been studied. Parameters used in this process are follow the method of first-principles. The comparative study gives some systematic trends between different parameter. The studies are useful to understand the behaviour and nature of these type of materials
