Non‐Additive Effects in the Elastic Behavior of Dental Composites
Source abstract
Abstract
The effective stiffness of dental composites consisting of a polymer and two fillers of different particle size is not predicted correctly by an additive approach (i.e. predicting the stiffness of a polymer and one‐filler system first). Better accordance with the experimental behavior is reached using a direct finite‐element calculation, which has been applied to this type of problem for the first time here.

2. By using short fibers or platelets one could in principle achieve the desirable reinforcement at already lower fillers’ loadings. However because of sharp edges short fibers are unwanted in many dental applications while platelets are difficult to disperse evenly.

16. Because of the 10 to 1 diameter ratio assumed for big and small spheres the computer models studied in this work were comprised of 103fs/fbsmall spheres per each big spheres.
17. We have found by using image analysis that the random hard‐fiber Percus–Yevick statistic is representative for “real” industrial fiber reinforced composites.[5 14]
