In this work the study of the steady state and dynamic behavior as well as the analysis of some controllability issues for reactive distillation columns, based on the applicability of the (equilibrium) element-based approach and thermodynamic issues, are presented.
A multiscale approach to the issue is proposed: An equilibrium element for finite element limit analysis representing keyed joints is coupled with a suitable submodel, which handles the complex stress states within the joint.
Our model explains systematic deviations from equilibrium element partitioning between the two phases exsolving from an initially homogeneous ternary feldspar during slow cooling.

The robust pointwise equilibrium polynomial element satisfying equilibrium in moment and shear at mid-span of an element is used in association with the cable element.
Thus, for the discretization of the spherical shell, with the help of an assumption about small displacements, the equilibrium finite element method based on internal force approximation is applied.
Stochastic equilibrium finite element (FE) foam models are used to study the influence of relative density and distribution of solid material between cell walls and edges on the elastic properties of foam materials.
The difference between the elastic strain energies at γ channels parallel and perpendicular to the stress axis is derived in closed form, which is used to evaluate the local equilibrium concentration of component elements.
This chapter presents a drum subjected to the two-belt tensions T1 and T2, the moment M necessary to prevent rotation, and a bearing reaction R. The forces acting on the differential element are calculated using the equilibrium of the element.
