Abstract
The aim of this work is to analyse the forces measured and stored during compression by using a computer.
We propose to calculate a “tabletibility index” which is very useful to classify the materials according to their capacity to give proper tablets by direct compression. We can also simulate the energy cycles in chosen experimental conditions, as it is not possible to compare cycles if the experimental conditions are not the same, which is very difficult to obtain.
In addition, this program calculates a “cohesion index” which is a dimensionless number. With this program and this cohesion index, it is possible to define the behaviour of different powder mixtures during compression very accurately. This is very useful to compare a batch to a reference as far as quality control, process control and formulation are concerned.
