    Thermodynamics of the quasiequilibrial growth of crazes (1981)
    Springer
    Journal of materials science 16 (1981), S. 35-44

    Notizen: Abstract By comparing the morphology and physical properties (averaged over the scale of 1 to 10μm) of a crazed and uncrazed polymer, it can be concluded that crazing is a new phase development in the initially homogeneous material. The present study is based on recent work on the general thermodynamic explanation of the development of a damaged layer of material. The treatment generalizes the model of a crack-cut in mechanics. The complete system of equations for the quasiequilibrial craze growth follows from the conditions of local and global phase equilibrium, mechanical equilibrium and a kinematic condition. Constitutive equations of craze growth-equations are proposed that are between the geometric characteristics of a craze and generalized forces. It is shown that these forces, conjugated with the geometric characteristics of a craze, can be expressed through the known path independent integrals (J, L, M,). The criterion of craze growth is developed from the condition of global phase equilibrium.

    The mechanical properties of PVC under high pressure (1983)
    Springer
    Journal of materials science 18 (1983), S. 3063-3071

    Thema: Maschinenbau
    Notizen: Abstract The deformation properties of PVC have been studied under high pressure. Craze initiation and yield criteria have been proposed. The brittle-to-ductile transition was observed between 1×107 and 2×107 Pa, which is a relatively low transition pressure compared to polystyrene. Deformation in the post-yield region occurred by neck formation and subsequent drawing to produce chain orientation. When PVC was exposed to the pressure-transmitting fluid, silicon oil, a strong environmental stress cracking effect was observed.

    Notizen: Three types of pressure dependent deformation processes have been observed for the short glass fiber reinforced composites of poly(vinyl chloride) (PVC). A unique deformation behavior, observed for the first time, features a sharp drop in stress followed by shear yielding in the matrix. Competitive pressure dependent failure processes in the composites are strongly affected by “debonding” at the fiber-matrix interface. A new general pressure dependent yield criterion for PVC and its composites was elucidated.

    Impact modification of poly(vinyl chloride) with chlorinated polyethylene II. Irreversible deformation (1984)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notizen: The mechanical behavior of chlorinated polyethylene (CPE)-modified poly(vinyl chloride) (PVC) has been determined. The nature of the irreversible deformation processes which are responsible for mechanical energy absorption has been investigated by optical and electron microscopic techniques. Addition of CPE results in a decrease in the shear band initiation stress and an increase in void density and stability. The crazing to shear banding transition is observed at a blend composition between 2 and 7 percent CPE at the strain rate employed. It has been established that voiding occurs in the CPE rubber phase. Voiding accounts for at least part of the increased energy absorption of the blend. The stability of the voids to coalescence and fracture is attributed to strong adherence of the CPE to the primary PVC particles.
