Abstract

Measurement of the flow stress of high density polyethylene (HDPE) and nylon 66 at strain rates of 103s-1 using a split Hopkinson pressure bar technique is discussed. The flow stress at a strain of 10% has been determined for both polymers at 20°C. The intrinsic errors involved in this technique are briefly reviewed. The results indicate that the flow stress of HDPE and nylon 66 were 50 MPa and 150 MPa, respectively, at strain rates of about 103s-1.
