Abstract
In this work, we demonstrate that current fatigue characterization tests with high density foam suffer from edge effects within the specimen, probably leading to early failures. Then a new specimen is designed to avoid this artifact. With this developed geometry, the stress is concentrated in the center of the specimen and not in the edge as given by the ASTM D1623-78 standard one. This allows getting the optimal fatigue life of PVC 4e-5 ℃-1 foam during tensile–tensile fatigue test.
