▎ 摘  要

NOVELTY - The method involves determining initial temperature of a graphene composite material laminated plate. Temperature stress is uniformly distributed. Graphite content, a substrate material parameter and a lamination angle are set. A Cauchy stress tensor is combined with a generalized Hooke law based on a first-order shear deformation theory. A hot bending equation of the graphene composite material is obtained based on a Hamilton principle. Grid-free kp-Ritz process is performed on a discrete graphene composite material to obtain a discrete bending equation. Numerical calculation is performed by a MATLAB (RTM: High-level technical computing language and interactive environment) to obtain inflection temperature of the graphene composite material laminated plate. USE - Graphene composite material laminated plate hot bending numerical calculating method. ADVANTAGE - The method enables realizing excellent mechanical performance of the graphene composite material and providing design assistance for aerospace and automobile. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a graphene composite material laminated plate hot bending numerical calculating method.
