Problem Statement:
To quantify the crystalline structure of polyethylene Abhiram Kannan define a procedure to measure the geometrical features of a lamella (in the crystalline structure. the extracted parameters are dimension and orientation parameters.
The polymers blown films for packaging application need to possess a combination of flexibility, toughness and ductility. These mechanical characteristics are most often mesured by two standard characterisation methods: the puncture resistance test (to mesure mechanical properties) and the tear resistance test (for the orientational tear property measurement).
Goal:
Our goal is to find the linkage between the film mechanica properties and their geometrical features.
Data Set
| Here | Samples | Samples characteristics | Dimensionality (Armstrons) | Orientation | Mechanical Properties |
|---|---|---|---|---|---|
| Number of parameters | 18 | 4 | 4 | 8 | 3 |
We have 12 geometrical parameters to describe the crystalline structure, and we have to link them to the 3 mechanical properties mesured.
structure-property problem Workflow
To tackle this problem we will have to reduce the number of geometrical parameters and find a correlation between the mechanical properties and the principal geometrical features.
