Derivation of temperature dependent mechanical properties of polymer foam core materials using optical extensometry

Derivation of temperature dependent mechanical properties of polymer foam core materials using optical extensometry

A methodology for determining the temperature dependence of Young’s modulus and Poisson’s ratio of polymer foams core materials is presented. The design of the test specimen is described in detail, covering the parasitic effects resulting from departures from the uniform strain condition. The mea...
