Sutherland, L.S. and Guedes Soares, C. (2005), “Impact on Single-Skin Marine Composites”, Maritime Transportation and Exploitation of Ocean and Coastal Resources, Guedes Soares, C., Garbatov, Y. e Fonseca, N. (Eds.), Taylor & Francis Group, London, UK, Vol. 1, pp. 535-542
Studies into the impact on single-skin marine laminates are outlined. Impact damage was seen to occur even at extremely low incident energies. Damage modes were multiple, complex and interacting. The impact response was dependant in a complex manner on a large number of material and impact event variables. Indentations followed Hertzian contact law at low forces, but then contact delamination lead to a linear stiffness relationship. Ongoing work includes studies into scaling, inertial interaction between plate and impacter masses, and quasi-static tests as a cheaper alternative to impact testing.
