Compressive strength is measured on materials, components, and structures. By definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely. The compressive strength is usually obtained experimentally by means of a compressive test.y definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely.

1 VX is primarily a liquid exposure hazard, but if it is heated to very high temperatures, it can turn into small amounts of vapor (gas). 2  Other methods have been experimentaly tested to produce a VX gas or mist.
The V-series agents are part of the group of persistent agents, which are nerve agents that can remain on skin, clothes, and other surfaces for long periods of time due to low volatility characteristics. The consistency of these agents is similar to oil; thus, the inhalation hazard is less than with the G agents.
