What are the characteristics of low order damage?

Low order damage is characterized by a slow pressure rise, leading to pushing and bulging damage rather than an instantaneous explosion. This type of damage occurs in scenarios where the chemical reaction or combustion happens gradually, allowing the pressure within a confined area to build up over time. Consequently, the structural materials are pushed outward and may bulge without experiencing complete failure or immediate destruction.

This gradual increase in pressure contrasts with higher order damage, where the pressures rise rapidly and can lead to explosive effects. In low order situations, the materials may deform, indicating significant stress but without reaching the point of catastrophic failure. Understanding this distinction is crucial for investigators, as it aids in determining the events leading to damage and the potential type of materials or conditions involved.

In summary, the defining feature of low order damage is its slow pressure rise, resulting in pushing and bulging rather than sudden destruction, which is why this answer is appropriate.
