Polymerization Fronts, Mechanical Constraint and Shrinkage Induced Residual Stresses in Bone Cement A one-dimensional coupled thermal-kinetics-viscoelastic model of in-situ polymerization

摘要

These results demonstrate that polymerization is highly complex and can give rise to high local residual strain energy and residual stresses. These effects may be a source of void nucleation and may explain interfacial porosity formation and cement fracture.
