Abstract:

We present experimentally obtained data on mechanical characteristics of fibers made from Rusar-type filaments under dynamic loading at the stress rate equals to 180 s^-1. Using improved approaches, we establish that the process of rapture of fibers under high-rate external loading may be subdivided into at least three stages. Single monofilaments form complex and compound object of a fiber. Under conditions of dynamic loading, multiple interactions between these single monofilaments may have a pronounced effect on the general properties of fibers.
