Static and dynamic mechanical properties of expanded polystyrene (2015, unknown): “22 MPa by Fatt and Park [37].”
A model to predict low-velocity impact response and damage in sandwich composites (2008, background): “The spring–mass models [19–21] and energy-balance models [2,20,22] are two of the few analytical solutions proposed to study the impact response of composite sandwich structures due to the complex interaction between the composite facesheet and core during deformation and failure.”
Plastic Deformation, Failure and Energy Absorption of Sandwich Structures with Metallic Cellular Cores (2010, methodology): “Hoo Fatt and Park [67] used the mass-spring model to predict the low velocity impact response of rigidly supported, twosided clamped, simply supported and four-sided clamped composite sandwich panels.”
Low-velocity impact failure of aluminium honeycomb sandwich panels (2008, methodology): “In reality, there exists an interaction between the local and global deformations [9].”
