TL;DR: In this paper, a displacement methodology for Mindlin elements, recently employed in the development of an efficient, four-node quadrilateral (MIN4), is the basis for a three-node, explicitly integrated triangular element (MIN3).

TL;DR: In this article, a variational principle is formulated for the inverse problem of full-field reconstruction of three-dimensional plate/shell deformations from experimentally measured surface strains, based upon the minimization of a least-squares functional that uses the complete set of strain measures consistent with linear, first-order shear deformation theory.

TL;DR: In this paper, a hierarchy of beam elements which include the effects of transverse shear deformation and rotary inertia is presented, and a series of constrained elements can be generated by imposing a continuous shear constraint condition on each member of the beam element family.

TL;DR: In this article, a refined zigzag theory is presented for laminated-composite and sandwich plates that includes the kinematics of first-order shear-deformation theory as its baseline.

TL;DR: In this article, a variationally consistent theory is derived from the virtual work principle and employs a piecewise linear zigzag function that provides a more realistic representation of the deformation states of flexible beams than other similar theories.
