Abstract
Transient dynamic behavior of a sandwich beam under thermal and impulsive loads has been researched in the
context of higher-order beam theory. The impulse load of blast type has been enforced on the top exponent of the sandwich
beam while it is in a thermal environment. The core of the sandwich beam is cellular with auxetic rectangular pattern, whereas
the layers have been built with the incorporation of graphene oxide powder (GOP) and are micromechanically introduced
through Halpin-Tsai formulization. Governing equations for the sandwich beam have been solved through inverse Laplace
transform style for obtaining the dynamical deflections. The connection of beam deflections on temperature variability, GOP
quantity, pulse load situation and core relative density has been surveyed in detail.
