Numerical Simulation of Functionally-Graded-Material Pipes Under Blast Loading
The behavior of thin-walled pipes made from Functionally Graded Materials (FGMs) under localized blast loading was examined through numerical simulation. FGMs are advanced composite materials, which possess continuous variation of material properties in the thickness direction. FGM pipes with varying thicknesses and diameters subjected to blast loads from a 0.1 kg TNT charge at varying stand-off distances of detonations were considered. The composition of the FGM pipes was defined by using the volume fractions of the constituent materials distributed across the thickness. The general rule of mixtures was used to predict the material property of the FGM pipes. The pipes were assumed to be restrained for both translation and rotation at their ends. Finite element modeling was conducted using the coupled Eulerian-Lagrangian (CEL) approach. The influence of constituent material gradation on blast response was also examined. The results of this investigation demonstrate a potential application of FGMs as thin-walled structural elements in the future development of a resilient pipeline infrastructure under extreme loadings.
