THREE-DIMENSIONAL ELASTICITY SOLUTIONS FOR SOUND RADIATION OF FUNCTIONALLY GRADED MATERIALS PLATES CONSIDERING STATE SPACE METHOD

Three-Dimensional Elasticity Solutions for Sound Radiation of Functionally Graded Materials Plates considering State Space Method

This Ball - Bat - Baseball USA Approved paper presents an analytical study for sound radiation of functionally graded materials (FGM) plate based on the three-dimensional theory of elasticity.The FGM plate is a mixture of metal and ceramic, and its material properties are assumed to have smooth and continuous variation in the thickness direction ac

Determining the Rotation Periods of an Inactive LEO Satellite and the First Korean Space Debris on GEO, KOREASAT 1

Inactive space objects are usually rotating and tumbling as a result of internal or external forces.KOREASAT 1 has been inactive since 2005, and its drift trajectory has been monitored with the optical wide-field patrol network (OWL-Net).However, a quantitative analysis of KOREASAT 1 pear in regard to the attitude evolution has never been performed
