Light combat vehicles are playing an important support role for both troops and other heavily armored combat vehicles. As such, they have a much greater risk than in previous roles of being subjected to transient loads such as impact and overpressure loads. Propagation of ballistic shock from an impacted region to the critical locations and attachment points for secondary systems can cause damage and misalignment to sensitive equipments contributing to malfunction and reduction of vehicle performance. The Army is actively engaged in a program to assess ballistic shock propagation damage and minimize sensitivity of secondary systems to such damage. The current investigation is devoted to the determination of response at critical locations of the vehicle hull structure of the APC M113 when subjected to a concentrated side-on nonpenetrating impact load.
