CA'V[underaccent underbar [below]KO: A SIMPLE 1-D LANGRANGIAN HYDROCODE FOR MS EXCELTM WITH AUTOMATIC GENERATION OF X-T DIAGRAMS

Hydrocodes are widely used to predict or simulate highly dynamic and transient events such as blast and impact. Codes such as GRIM, CTH or AUTODYN are well developed and involve complex numerical methods and in many cases require a large computing infrastructure. In this paper we present a simple 1-D Langrangian hydrocode developed at the University of Cambridge, called CA'V[underaccent underbar [below] 'KO written in Visual Basic. The motivation being to produce a code which, while being relatively simple, is useful for both experimental planning and teaching. The code has been adapted from the original KO code written in FORTRAN by J. Borg, which, in turn, is based on the algorithm developed by Wilkins [1]. The developed GUI within MS ExcelTM and the automatic generation of x-t diagrams allow CA'V[underaccent underbar [below] 'KO to be a useful tool for quick calculations of plate impact events and teaching purposes.
