Abstract: LangMod is an interactive software implementation of a modified Langlie sequential test strategy. Similar to the Up and Down (Bruceton) method, the Langlie strategy can be used in V50 ballistic limit testing to select test shot velocities based on previous velocities and responses. The software includes graph frames to show the data in shot sequence and the response curve as a function of velocity when the appropriate data is obtained. Parameter estimates are also provided to include the mean and standard deviation of the response curve as well as the V50 estimate and V50 standard deviation.
