High Velocity Impact Analysis on “Composite Material Block” Using FEM Approach
نویسندگان
چکیده
The failure of an AL6061-T6 and Kevlar-29 composite plate under high-velocity impact from an S-S (structural Steel) projectile tool was investigated using the nonlinear explicit finite element software, ANSYS AUTODYAN. Two velocity ranges 350 m/s and 700 m/s were used for FEM simulation. It was analyzed that AL6061-T6 is more resistant than KELVAR 29 at both ranges but Kevlar 29 is light in weight than AL6061 and have more application in aviation industry. The composite laminate and the tool were venerated by solid FEM elements. The contact between the tool and plate was simulated using a surface-to-surface eroding contact algorithm. It was also observed that tool dimension and mass play important role in failure conditions.
