The investigation of mechanical properties of materials at high strain rates has become increasingly important in recent years. To establish the dynamic behavior of materials the acquisition of full-scale deformation field plays a key role. Traditional strain measuring techniques rely on the use of extensometers and strain gauges. But there are certain limitations of traditional measuring techniques, such as frequency response, rate of loading, and range of strain in which situation non-contacting measuring technique is highly preferred. This paper presents a straightforward measuring technique using image analysis to obtain the deformation of Kevlar 49 fabric over a range of strain rate from 20 to 170 s-1. Based on image analysis results the stress-strain curves of Kevlar 49 fabric at different strain rate were constructed and compared with those based on actuator (LVDT) measurement. Good agreement was achieved between image analysis and LVDT measurement.
