    Temperature Dependent Mechanical Characterisation of Styrene-Acrylonitrile
    (RAPRA TECHNOLOGY LTD, 2009) GÜLLÜOĞLU, ARİF NİHAT; Solakoglu, Ilker; Ataoglu, Senol; Gulluoglu, Arif N.; Kadioglu, Necla
    Poly(styrene-co-acrylonitrile) (SAN) which is a random, amorphous, linear copolymer produced by copolymerising styrene and acrylonitrile was investigated experimentally. Specimens were supplied from a private company and they were analysed using a differential scanning calorimetry machine (DSC). The behaviour of the material in creep, tension and hardness experiments was investigated experimentally at several temperatures. The creep response of SAN was also evaluated.

    An Analytical Model for Compressive Creep Behavior of HDPE Used in Plastic Pipe Manufacturing
    (TAYLOR & FRANCIS INC, 2008) GÜLLÜOĞLU, ARİF NİHAT; Sezer, S.; Ataoglu, S.; Gulluoglu, A. N.; Kadioglu, N.
    The creep behavior of high-density polyethylene has been studied by low compressive creep tests, and empirical results were analyzed and compared with analytically predicted results. The tests are performed upon ASTM standard specimens at various stress levels in the linear region. After these analyses, a mathematical model is derived and used to predict creep strain for long periods of time from the strain-time data obtained at different stresses over a time interval of 24h.
