โœฆ Synopsis

Three dimensional simulation of hypervelocity impacts on space structures places extreme demands on even supercomputer resources. This is due in large part to the fact that conventional Eulerian and Lagrangian codes are ill-suited to model debris cloud evolution. To reduce the computer time and memory requirements of oblique impact simulations, a three-dimensional elastic-plastic particle dynamics model of debris cloud evolution has been developed. This numerical model has been linked to an Eulerian hydrocode and a Lagrangian structural code, and applied in the simulation of oblique hypervelccity impacts on Whipple shield-protected structures.

This paper assesses a Whipple shield impact simulation method which is both accurate and computationally efficient. The paper documents the simulation methodology and results of Whipple shield simulations at an oblique impact angle of 30 ยฐ . These results are compared with HVI experiments to demonst
