Sub-cell-free weighted least-squares integration methods with and without stabilization terms for higher-order shear deformation analysis of isotropic plates

Chien H. Thai, Hung Q. Tran, Duong D. Vu

Short summary

A new sub-cell-free weighted least-squares integration (SCF-WLSI) framework for plate analysis eliminates background meshes, with a stabilized variant (s-SCF-WLSI) uniquely removing spurious spikes in vibration mode shapes without sacrificing eigenvalue accuracy.
