  text: <jats:title>Abstract</jats:title><jats:p>Polycarbonate (PC) is an amorphous
    polymer that is an extremely robust material with a high tenacity, and thus suitable
    for a lightweight construction with glass‐like transparency. Due to these advantageous
    properties, PC is often used in industry for example in medical devices, automotive
    headlamps, sporting equipment, electronics, and a variety of other products. PC
    is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable
    material models have to take into account the various resulting experimental effects.
    For those reasons, we investigate PC specimens under uniaxial and biaxial loading
    by using different stretch rates and loading scenarios. In addition to that, we
    propose methods for optical measurement of local stretches to obtain the approximated
    local true stress. In future work, the displacement fields and the resulting reaction
    forces will be used for parameter identification of constitutive equations.</jats:p>
