Abstract : There are several types of firing tests of cannonballs. In ground firing tests, cannonballs without gunpowder charged
are fired against sand heap. When a cannonball collides into sand, the cannonball’s penetration depth, stress and sand
temperature depend on the sand properties. Sand tends to become harder than before after plenty of cannonball firing. This is
because kinetic energy of a cannonball is dissipated due to friction. Thus, analysis of temperature in sand is important. In this
study, a method of sand temperature analysis is suggested.It is found that temperature rises by about 150℃, and the
temperature risein sand depends highly on sand density. The results obtained in this study can be used in management of
impact test sites.
