Representative volume element
-
This study presents a novel application of mesh-free method using the smoothed-radial basis functions for the computational homogenization analysis of materials. The displacement field corresponding to the scattered nodes within the representative volume element (RVE) is split into two parts including mean term and fluctuation term, and then the fluctuation one is approximated using the integrated radial basis function (iRBF) method.

Lightweight structures with soft inclusion material, such as hollow core slabs, foam sandwich wall, pervious pavement are widely used in construction engineering for sustainable goals. Voids and soft inclusion can be modeled as a very soft material, while the main material is modeled with its original rigidity, which is so much higher than inclusion’s one.

Reduction of Effective Arterial Volume In many forms of edema, the effective arterial blood volume, a parameter that represents the filling of the arterial tree, is reduced. Underfilling of the arterial tree may be caused by a reduction of cardiac output and/or systemic vascular resistance. As a consequence of underfilling, a series of physiologic responses designed to restore the effective arterial volume to normal are set into motion. A key element of these responses is the retention of salt and, therefore, of water, ultimately leading to edema.
