摘要:
This contribution is concerned with the modelling of PMMA-based bone cement polymerisation process and the associated heat effect. While existing models use description in terms of the so-called polymerisation fraction to fit the experimental data, the new model is constructed in such a way as to mimic the chemical processes taking place in the cement dough. The important phenomena are identified and the mathematical formulation is proposed. (c) 2004 Elsevier Ltd. All rights reserved.
