    4. True-False, You must justify your answer for full credit.
    a) Dislocations can appear in amorphous materials.
    b) A Voight model fully describes the mechanical behavior of most real polymers.
    c) The compliance of a testing frame is only important when one is testing a really compliant material.
    d) xx =  * xx
    e) Hole-drilling is a good way to fix a crack, because the hole adds compressive stresses to the crack tip.
