This present paper presents a lattice approach to model the influence of cracking on flow in concrete. An earlier mechanical lattice model based on the Voronoi tesselation with a damage-plasticity constitutive model was combined with a new dual lattice of conduit elements for flow analysis. The diffusivity of the conduit elements depends on the crack-opening obtained from the mechanical lattice...

This paper presents a lattice approach to model the influence of cracking on inviscid flow in concrete. A mechanical lattice model based on a damage-plasticity constitutive model was combined with a new dual lattice of conduit elements for flow analysis. The diffusivity of the conduit elements depends on the crack-opening obtained from the mechanical lattice. The coupled lattice model was appli...

naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. the main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. in t...

Many mechanical systems consist of continuum mechanical structures, having either linear or nonlinear elasticity or geometry, coupled to nonlinear oscillators. In this paper, we consider the class of linear continua coupled to mechanical pendula. In such mechanical systems, there often exist several natural time scales determined by the physics of the problem. Using a time scale splitting, we a...

The lithium-ion battery (LIB) is widely used as an energy storage device for electric vehicles (EV) due to its advantages, such high density and long lifespan. However, LIB EV can be exposed mechanical abuse vehicle collision, which causes thermal runaway extreme deformation. Therefore, it necessary predict the internal short circuit (ISC) of cell under loading conditions analyze mechanical, el...

This paper reports result of calculation and experimental realization of an electromechanical system that consists of a high-Q mechanical oscillator parametrically coupled in the manner of a capacitive transducer with a radio frequency (RF) circuit, which is in turn inductively coupled with another RF circuit. The system operates in the resolved sideband regime when the mechanical oscillator's ...
