TL;DR: In this paper, a variationally consistent weak coupling method for thin-walled shell patches is proposed to ensure a corresponding geometric continuity in the deformed configuration and a correct transfer of bending moments across the interface.

TL;DR: This work presents a robust variationally consistent Nitsche-type formulation for thin shells at large deformations that weakly enforces coupling constraints at trimming curves, and presents a set of algorithms that enable automatic interaction of trimmed shell analysis with CAD data structures based on the STEP exchange format.

TL;DR: In this article, a displacement-based layerwise theory is proposed to model the transverse displacement field at the interface between plies of different fiber angle orientation, and a multiple model analysis is employed to simulate laminates with existing delaminations.

TL;DR: The non-symmetric variant of Nitsche's method was recently applied successfully for variationally enforcing boundary and interface conditions in non-boundary-fitted discretizations.

TL;DR: In this article, the authors developed a new systematic creep analysis model to calculate the friction of a ball screw and established a proper transformed coordinate system to investigate the friction behavior better, in which the creep parameters can be easily obtained, such as the vertical creep ratio, the horizontal creep ratio and the spin ratio acting on three contact areas.
