Microscopic simulations of fracture dissolution
[1] Microscopic simulations of fracture dissolution are reported, taking account of the explicit topography of the pore space, the transport of reactants and products, and the chemical kinetics at the solid surfaces. A three-dimensional numerical model has been constructed, in which the fluid velocity field is calculated with an implicit lattice-Boltzmann method, and the transport of dissolved ...
متن کاملMacroscopic fracture characteristics of random particle systems
This paper deals with detennination of macroscopic fracture characteristics of random panicle systems. which represents a fundamental but little explored problem of micromechanics of quasibrittle materials. The panicle locations are randomly generated and the mechanical properties are characterized by a triangular softening forcedisplacement diagram for the interparticle links. An efficient alg...
متن کاملSimulation of Pedestrian Dynamics with Macroscopic and Microscopic Mathematical Models
Here, we collect two parts of a research project on the pedestrian flow modeling. Rapid growth in the volume of public transport and the need for its reasonable, efficient planning have made the description and modeling of transport and pedestrian behaviors as important research topics in the past twenty years. First, we present a macroscopic model for the pedestrian flow based on continuum mec...
متن کاملPrediction of plane strain fracture of AHSS sheets with post-initiation softening
In this investigation, the three-parameter Modified Mohr–Coulomb (MMC) fracture model and the determination of the material parameters are briefly described. The formulation of the post-initiation behavior is proposed by defining both the explicit softening law and the incremental damage evolution law. As opposed to the existing attempts to simulate slant fracture with material weakening before...
متن کاملFracture Failure Mechanism
The present study investigates the failure mechanisms of industrial fiber materials 13 a custom designed fiber cutting performance test bench. The fracture morpholog 14 fibers are examined by scanning electron microscopy. The analysis reveals that fiber cutting can be 15 distinguished according to four distinct stages of fiber failure represented by shearing, cutting, 16 brittle fracture, and t...
