Abstract:Failure mechanism of rigid polyurethane foam (RPUF) treated under different conditions was studied by means of experiments and numerical simulation. Thermal degradation mechanism of RPUF under different temperatures was characterized by thermogravimetric analysis‐Fourier transform infrared spectrometry coupled with gas chromatography–mass spectrometry (TG‐FTIR‐GC–MS) in air and nitrogen atmosphere, respectively. And the vibration failure mechanism of RPUF was analyzed by finite element analysis (FEA) and exten… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
