Abstract: The characterization of plastics for engineering purposes necessitates considerably testing than is typical for metals primarily because of time, temperature, moisture, and aging effects on the material behavior. With the increasing number of plastic structural components, it can be expected that the need to measure service strains on these materials will increase correspondingly and the strain gage application technology must be advanced accordingly. It is very important for polymeric materials to determine the Young’s modulus and the Poisson’s ratio using the strain gage rosette. This paper presents the measurements using the strain gage rosette on three different used plastics: ABS, PP and PS. The strain measurement on a plastic or composite test object will frequently call for much greater skill, expertise, and knowledge of mechanics than that typically required with the structural metals.
Keywords: polymeric material, strain gage rosette, elastic constants
