## Abstract True constant strain rate tensile tests of polypropylene up to 2% initial strain were performed to investigate the strain rate dependency of the initial stress–strain gradient __d__σ/__d__ε with the aid of “slack grip.” The experimental results fairly agree with even the simplest mechan
