Measurement of mechanical properties is very important in material science research area.
Introduction How to measure mechanical properties of materials and biological tissue noninvasively is an important issue in material science, non-destructive test, and medical diagnosis.
A usual approach for noninvasive measurement is to quantify responses of materials stressed by external force.

The resulting material is promising as a sorbent of heavy metal ions and packing materials for transportation and storage.
A recognized disadvantage of starch-based materials is their sensitivity to moisture.
For creation of foamed materials based on it, it is necessary to obtain a water-soluble form.

Such structures are relevant for use in various branches of technology, in particular aircraft construction, mechanical engineering, materials science, which require the manufacture of products with increased operational properties at minimal financial costs, as well as reducing the cost of finished products [7].
Thus, the study of the properties of powder materials using computer modelling is an urgent task of materials science.
