An analysis of shock conditions arising from an oblique impact between two solids

A method for establishing the shock conditions in two solids resulting from an oblique impact of one solid onto the other is presented. The theoretical development is limited to impacts that produce attached shocks in the two solids. Five non-linear equations are deduced which must be solved simultaneously with a numeric solver function such as MATLAB's 'fsolve' function. Multiple impact scenarios between two solids over a range of obliquities are analyzed and compared to CTH hydrocode predictions and normal impact Rankine-Hugoniot theory to verify the approach.
