Finite element simulation of penetration into geological targets
The finite element method has been applied to study the projectile penetration process into geological targets. To illustrate the solution procedure, two example problems involving conical nose steel penetrators into sea ice and antelope tuff are presented. Details of the numerical treatment using the computer code PRONTO 2D are given. Good agreements between numerical and experimental results are observed. Although the examples are limited to normal impact problems in which the axis of the penetrator is perpendicular to the target surface and where no angle of attack for the penetrator is allowed, some thoughts regarding ways to deal with nonnormal three-dimensional penetration problems are discussed. 9 refs., 20 figs.
