    University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Author : Rajdip Roy; Lu Qi; [2009]
    Keywords : Stress Relaxation; Viscoelastic Model; Elastic Modulus Relaxation; Tensile test; FE-modeling;

    Abstract : In this master degree thesis the time dependent deformation of packaging material is studied. Mechanical experimental tests were carried out to monitor the stress decreasing rate on paper. Several viscoelastic models were constructed using various theories and compared with the obtained experimental stress relaxation. READ MORE
