Analytical and numerical methods have been developed to approximate
|
||
|
|
the eccentric impact response of deformable bodies. The eccentric
|
||
|
|
impact response is commonly known as {\em slapdown} since the
|
||
|
|
off-center impact gives the body a rotational velocity which causes
|
||
|
|
impact at the opposite end. A code, \SLAP , has been written to
|
||
|
|
approximate the slapdown behavior of deformable bodies. The body is
|
||
|
|
idealized as a three degree-of-freedom system with nonlinear impact
|
||
|
|
behavior.
|
||
|
|
|
||
|
|
Several parameters of interest to the analysis and design of laydown
|
||
|
|
weapons were studied to determine their effects on the secondary
|
||
|
|
impact velocities (slapdown). Parameters studied are aspect ratio of
|
||
|
|
the body, stiffness of the initial impact, and friction between the
|
||
|
|
target and the body. Rules for applying the results of scale model
|
||
|
|
tests to full scale bodies are developed and confirmed for nonlinear
|
||
|
|
spring behavior.
