Study on static/dynamic mechanical properties and constitutive relation of multilayered composite-function cloth

摘要

Quasi-static tests via MTS test system and SHPB experiments on the physical properties of composite function cloth were carried out. Basic mechanical parameters and stress-strain curve of the cloth were obtained through experiments. The static and dynamic constitutive model was presented based on necessary analysis of deformation behavior of materials, strain-rate-related effects and destruction properties. It provides bases for engineering applications of these materials and further improvement. The results show that: under quasi-static loading and shock loading, strain rate effect is obvious with increasing strain rate and higher slope of stress-strain curve.
