Two Experimental Approaches for Investigation of Nonlinear Elastic Properties of Polymers and Polymer-Based Composites

Abstract

The development and fabrication of novel composite materials requires accurate investigation of their mechanical properties. Although various approaches are well-established for investigation of linear elastic properties, there are only few methods that can be applied for study of nonlinear ones. In this report we describe and compare the performance of two different experimental approaches aimed for investigation of nonlinear elastic properties of glassy polymers and polymer-based composites.
