As　a　new　addition　to　lightweight　composite　structures,　the　sandwich　cylindrical　shell　with　a　metallic　wire　mesh　core　has　emerged　as　a　promising　solution　for　thermodynamic　performance　analysis　at　elevated　temperatures.　The　intricate　interwoven　cellular　formations　within　the　metallic　wire　mesh　pose　difficulties　for　thermo-mechanical　modeling　and　property　evaluation.　First,　the　constitutive　models　employed　to　characterize　hysteresis　phenomena　were　presented,　comprising　isotropic　elasticity,　Bergstrom-Boyce　model,　Ogden　hyper-elasticity,　and　parameter　identification　through　mechanical　examinations　at　varying　temperatures.　Second,　the　finite　element　modeling　of　cylindrical　shell　structures　was　determined　for　modal　and　steady-state　dynamic　analyses.　Third,　the　experimental　procedures　were　carried　out,　including　the　preparation　of　the　sandwich　cylindrical　shell　and　the　dynamic　testing　platform.　The　first-order　natural　frequency　of　the　cylindrical　shell　structure　is　close　to　the　resonance　frequency　of　the　dynamic　test　results,　with　a　maximum　error　of　6.5%,　demonstrating　the　accuracy　of　the　simulation　model.　When　compared　to　the　solid-core　cylindrical　shell,　the　average　insertion　loss　of　the　sandwich　cylindrical　shell　structure　within　the　frequency　range　of　10–1000　Hz　at　room　temperature　is　up　to　11.09　dB.　Furthermore,　at　elevated　temperatures,　the　average　insertion　loss　of　the　sandwich　cylindrical　shell　decreases　but　fluctuates　as　the　temperature　changes.　©　2023　Chinese　Society　of　Aeronautics　and　Astronautics
