Flash X-ray radiography of internal damage in soft cellular materials during in...
Fíla, Tomáš; Falta, Jan; Koudelka, Petr; Šleichrt, Jan; Krčmářová, Nela; Duarte, IsabelProcesses of internal damage development during localized dynamic penetration represent a crucial mechanism important for relevant analysis of deformation and failure of plates and sandwich panels under high strain rate conditions. Soft cellular materials are of special importance as the internal damage defines mode of collapse and energy absorption capabilities. In this paper, a fast X-ray radiography is emplo...
Dynamic penetration of cellular solids: experimental investigation using Hopkin...
Šleichrt, Jan; Fíla, Tomáš; Koudelka, Petr; Adorna, Marcel; Falta, Jan; Zlámal, Petr; Glinz, Jonathan; Neuhäuserová, Michaela; Doktor, TomášLight-weight cellular solids, such as aluminium foams, are promising materials for use in ballistic impact mitigation applications for their high specific deformation energy absorption capabilities. In this study, three different types of aluminium alloy based in-house fabricated cellular materials were subjected to dynamic penetration testing using an in-house experimental setup to evaluate their deformation a...
