Conclusions
-
1.
The examined material, i.e., woven organic plastic, shows almost linear behavior both at room and elevated temperatures.
-
2.
The dependence of the strength of the material on loading rate at various temperatures in nonmonotonic as a result of a change of the failure mechanisms.
-
3.
The specific strain rate ranges in which failure is the result of gradual damage cumulation and strength increases with increasing loading rate have been determined. It is recommended to use the examined material in these ranges in the high-speed loading conditions.
-
4.
The dependence of the limiting elongation of the material on strain rate at various temperatures was determined by means of experiments and described theoretically using the previously constructed model.
