Adaptive periodical representative volume element for simulating periodical postbuckling behavior

Abstract: SUMMARYFinite element method (FEM) with fixed representative volume element (RVE) encounters some difficulties in simulating the periodical postbuckling behaviors of infinite long beam or infinite large film on soft substrate under compression, because the wavelength and pattern of buckling are not known before simulation and will change with the increase of compression strain. In this paper, an adaptive periodical RVE is constructed in a mapping space to avoid remeshing in the real space, and the mapping coef… Show more

“…With this choice, the buckling wavelength predicted by ABAQUS, L cr | F EM , was a discrete value that was equal to or directly adjacent to the expected value for L cr | th . A more elegant approach would have been to use Bloch wave analysis for a unit cell of height H (where H can take any value) [8,2] or the adaptive representative volume element recently proposed by Ton et al [37]. However, since the main goal of these buckling simulations was to validate the buckling theory and to select appropriate volume fractions for non-dilute composites, the approach described above is sufficient.…”
