An explosive separation joint system having an expandable tube containing a mild detonating fuse (MDF) in separable portions of the joint. The MDF extends into a detonation manifold at a first port, an end of the MDF having booster bonded thereto. An external initiating ordnance transfer line enters the manifold at an initiating ordnance (IO) port, has an IO end tip and provides a detonation impulse train where each detonating component is axially aligned within a passageway with the next detonating component. In embodiments, particular detonating components of the detonation train are fixed in place where other detonating components are movable. Each detonating component that is not in direct contact with a preceding detonating component in the detonation train is in direct linear access.

A shock simulation test apparatus and method utilize a test plate and formed explosive charges to sever or penetrate one or more portions of a suspended test plate in order to subject any attached test item(s) to a realistic pyroshock stimulus. One or more shock measurement sensors, such as accelerometers, may be attached to the test plate or the test item(s) to measure the response to this shock stimulus. The apparatus and method is flexible in that many different scenarios can be simulated from different test plate materials, charge sizes and types. This method replicates actual end-use source shock environments typical in aerospace applications, but can be extended to any industry having a pyroshock environment and test requirement.
