    Dimensional variations of two spherical polymeric particles during sintering (1981)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 21 (1981), S. 582-585

    Notes: A quantitative “Round Neck” (RN) model based upon volume balances and considerations of surface tension phenomena is proposed for simulation of coalescence of two spherical polymeric particles; during sintering. This model and an early model developed by Frenkel are compared and evaluated against experimental data to show their suitability to simulate geometrical variations of a particle pair during sintering.

    Wall thickness distribution in thermoforming (1979)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 19 (1979), S. 946-951

    Notes: This paper presents an isothermal, one-dimensional model predicting wall-thickness profiles of vacuum- or pressure-formed products. After formulating a set of simplifying assumptions theoretical analyses of forming into conical and truncated (deep and shallow) molds are presented and discussed. Fair agreement is found between previously reported experimental results and the proposed theoretical models.

    Softening temperature of glassy polymers as affected by residual stresses (1979)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 19 (1979), S. 223-225

    Notes: Heat deflection temperature and Vicat softening point of polystyrene and polymethylmethacrylate with various thermal histories were measured. Surface residual stresses were characterized by liquid crazing. Residual stress profiles across the sample thickness were also measured. It is suggested that the softening behavior of glassy polymers is affected by the state of the residual stresses in addition to the traditionally accepted free volume approach.

    Newtonian sintering simulator of two spherical particles (1983)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: Sintering of amorphous polymer particles above their glasstransition temperature is a slow coalescence process in which surface tension is the main driving force, tending to decrease the total surface area, resisted by the polymer viscosity. The shape, and therefore the boundaries of the coalescing particles, change with time. A numerical finite-element method (FEM) was used to solve the momentum and continuity equations for a coalescing spherical-particles pair. The solution obtained describes a limited sintering time interval with reasonable agreement. Future modifications of the solution technique are suggested in order to extend its validity to longer sintering periods.

    Sintering rheology of amorphous polymers (1981)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: The activation energy for sintering of poly(methyl methacrylate) particle pairs is shown to be similar to their activation energy for Newtonian flow. Sintering progress with time is in good agreement with the Frenkel's coalescence theory. Typical sintering shear rates are shown to be very low and potential energy change (two particles) is small in comparison with the surface energy change. These results lead to the conclusion that the coalescence sintering mechanism of amorphous polymers above their glass transition temperature is essentially a Newtonian viscous flow mechanism where surface tension is the major driving force. A periodical phenomenon associated with sintering progress with time is reported and a supporting mechanism is proposed.
