Experimental and numerical analysis correlation of hail ice impacting composite structures
40th Structures, Structural Dynamics, and Materials Conference and Exhibit
Many composite aircraft structures such as fuselage and wing skins, engine nacelles, and fan blades are situated such that hail ice impacts are a realistic threat. To investigate this threat, high velocity impact experiments and subsequent numerical analyses were performed to study hail ice impacts on composite structures. As hail ice is not a well characterized impact material, cast ice spheres made to simulate hail ice were projected onto a force measurement transducer system with thedoi:10.2514/6.1999-1366 fatcat:l4n5xizkxndjvne5rtsioszdri
