Improved dynamic analysis of shear deformable shells using the hybrid displacement boundary element method
THA Naga, EM Elsheikh - Engineering Analysis with Boundary Elements, 2024 - Elsevier
In this paper, the dynamic analysis of shear deformable shells was conducted using the
hybrid displacement boundary element method (HD-BEM). The approach involved utilizing
the fundamental solution as a trial function to derive the 8-node element stiffness matrix,
while approximating the boundary variables with quadratic shape functions. To ensure
efficient computations and avoid singular integrals, the source points were strategically
positioned outside the domain. For accurate calculations of the proposed 8-node element …
