RISOn the Approximation of the Full Mass Matrix in the Rotational-Coordinate-Based Beam Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel approach is developed to approximate the full mass matrix in the rotational-coordinate-based beam formulation, which can improve the efficiency of calculating its inverse in dynamic analyses. While the rotational ...
An Efficient Galerkin Averaging-Incremental Harmonic Balance Method Based on the Fast Fourier Transform and Tensor Contraction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An efficient Galerkin averaging-incremental harmonic balance (EGA-IHB) method is developed based on the fast Fourier transform (FFT) and tensor contraction to increase efficiency and robustness of the IHB method when ...
