Non-linear thermal response of sandwich panels with a flexible core and temperature dependent mechanical properties

Significance of output:

Foam cored sandwich structures are often subjected to both mechanical and thermal loading. The mechanical properties of polymer foams reduce at elevated temperatures. Consequently, a linear and stable load response at room temperature may change to being nonlinear and unstable at higher temperatures, affecting applications from aerospace to wind turbine blades. A numerical model including thermo-mechanical interactions and thermal degradation is presented. The work has led to funded projects value GBP 0.8 mill with academic participation from Denmark, UK and Israel, supported by LM Wind Power, DIAB, E-ON, US Navy and the Danish Council for Independent Research.
