Pressure Effects and Surface Cracks in a Rubbery Particulate Composite

Abstract

Cracks developed during manufacturing, handling and storage of rubbery particulate composites. Previous tests used single edge notched tension (SENT) specimens. In this work, surface cracked specimens are compared with the previous results. Results for ambient and pressurized test conditions are also compared. Pressure affects fracture behavior by suppressing void nucleation, growth, and coalescence. Both initiation of growth and subsequent growth rates are affected. Applying ambient test data can result in overly conservative predictions.
