This paper details the finite element (FE) stress analysis of a conceptual 105-mm kineticenergy (KE) projectile launched with a composite sabot that is subjected to both axial andtorsion loadings. The dynamic FE simulation uses input from IBHVG2 and Bandslip topredict the base pressure history and the spin history, respectively. The FE resultsindicate that the projectile spin history during gun launch has a significant effect on thesabot-penetrator interface shear tractions and consequently, the sabot structural integrity.
