Hybrid plate vibration models for coarse-mesh analysis

摘要: Abstract Hybrid FE combined membrane + bending rectangular plate vibration models (7 11)βC0 and 17)βC1 are proposed for computer assisted identification of modes high degree efficient coarse-mesh analysis. Accurate yet cost effective hierarchial matrix generation capability is provided through the expedient an exact analytical integration algorithm, which circumvents many time consuming steps associated controversies numerical quadrature interactions, while yielding computational economy comparable to that required by single-point Gaussian rule. Samples experiments corroborate present development confirm accuracy with rapid convergence characteristics.
