Fully adherent fiber-matrix FEM formulation for geometrically nonlinear 2D solid analysis
TL;DR: In this paper, an accurate finite element formulation for the analysis of two-dimensional reinforced elastic solids that develop both small and large deformations is presented, which has four important features: (i) an efficient strategy for modeling fibers immersed in a continuum without introducing new degrees of freedom; (ii) no coincidence among fiber and continuum discretization nodes; (iii) the use of curved fiber elements and isoparametric solid elements of any order; and (iv) a fully satisfied adhesion condition between fibers and matrices.

A geometrically nonlinear FEM formulation for the analysis of fiber reinforced laminated plates and shells
TL;DR: In this article, an alternative finite element (FE) formulation for the analysis of fiber reinforced laminated plates and shells developing small and large deformations is presented, which does not increase the number of degrees of freedom of the analyzed shell and do not require the necessity of matching nodes in the discretization of fibers and matrix.

Large displacement analysis of three‐dimensional beam structures
TL;DR: In this article, an updated Lagrangian and a total Lagrangians formulation of a three-dimensional beam element are presented for large displacement and large rotation analysis, and it is shown that the two formulations yield identical element stiffness matrices and nodal point force vectors.
