TL;DR: In this paper, a simulation procedure for vehicle-substructure dynamic interactions and wheel movements is presented, where the vehicles and substructure systems interact though wheel-rail interfaces satisfying two compatibilities, i.e., the equilibrium of contact forces including a lateral creep damping force and the geometry relating wheel and rail movements, rail irregularities and local contact deformations.

TL;DR: In this paper, a quasi-conforming formulation of 4-node stress resultant shell element is presented for the linear static and dynamic analysis of composite plates and shells, which is applicable for moderately thick and thin composite shells.

TL;DR: In this article, the effect of volume fraction of the constituent materials in the mechanical behavior of FGM plates and shells is investigated, where the material properties are assumed to be varied in the thickness direction according to a sigmoid function in terms of the volume fraction.

TL;DR: In this article, the authors investigated the natural frequencies and buckling loads of functionally graded material (FGM) plates and shells, using a quasi-conforming shell element that accounts for the transverse shear strains and rotary inertia.

TL;DR: In this article, a co-rotational 8-node degenerated thin-walled element with no rotational degrees of freedom is presented to demonstrate the solutions of linear and geometrically non-linear analysis for plate and shell structures.
