two are diagnostic and tell us about the static relation between different parameters: namely the gas law, which gives the relation between pressure, density, and temperature, and the hydrostatic equation, which shows the relationship between the density of the air and the change of pressure with...
The latter relate to standard beam theory but are embedded in a continuously rotating frame. A set of numerical examples show that the element provides an excellent numerical performance.Access through your organization Check access to the full text by signing in through your organization.

As the main driving mechanism of a hybrid robot, the parallel mechanism is a nonlinear time-varying system. The load inertia of its actuated joints changes with the configuration of the robot. Analyzing and fitting the inertia variation is of great signi
The proposed model is based on the Theory of Porous Media (TPM), a consistent approach to describe geomaterials in a macroscopic frame [1]. Assuming quasi-static conditions, strains in the porous soil body are due to an elasto-plastic work-hardening model, whereas the constitutive properties ...
This formulation transforms the magneto-dynamic field problem expressed by Eq. (1) to a magnetostatic complex field problem with induced currents. In the chosen approach the rotor is fixed in the stator reference frame and an equivalent conductivity is assigned to the rotor bars to take into con...
Several formulations have been proposed for analyzing the nonlinear deformation of beams in static and dynamic MBSs. The floating frame of reference [9], the incremental finite element [29, 32], the large rotation vector [39], the geometrically exact beam [2, 17, 39–41] and ...

Unreinforced masonry structures are vulnerable to seismic actions and frequently exhibit partial or global out-of-plane wall collapse when subjected to large intensity earthquake shaking. The installation of timber strong-backs connected to the masonry surface with mechanical fasteners is a reversible and...
This study presents a simple formulation to treat large deflections by the finite element method. The proposed formulation does not use the displacement concept. It considers position as the main unknown variable of the problem. The strain determination is performed directly from the proposed position...
