An energetic formulation of a gradient damage model for concrete and its numerical implementation
(Pergamon-Elsevier Science Ltd, 2018-12)
The energetic formulation of a rate-independent system assumes that the evolution of the system is driven by two scalar-valued functions: the storage energy functional and the dissipation pseudo-potential. The evolution ...
Mathematical formulation of a new linear surface element for the modeling of axisymmetric magnetic field problems
(IOS Press, 2019-09)
There are currently two main trends in solving magnetic field problems, numerical methods, of which the Finite Element Method (FEM) is undoubtedly the most popular, and analytical methods, of which there is a great diversity ...
Fluid stabilization of the u−w Biot's formulation at large strain
(John Wiley & Sons Ltd, 2020-11)
Dynamic problems of fluid-saturated soils have to be assessed through a complete formulation where dynamic terms take place. The main dynamic Biot's formulation, the (Formula presented.), is employed widely in the literature ...
Numerical simulation of mushrooms during freezing using the FEM and an enthalpy: Kirchhoff formulation
(Springer, 2011-06)
The shelf life of mushrooms is very limited since they are susceptible to physical and microbial attack; therefore they are usually blanched and immediately frozen for commercial purposes. The aim of this work was to develop ...
