3D LATTICE MODELING OF TENSILE TEST ON SIMULATED CEMENT PASTE AT MICROSCALE

摘要：

Looking into materials is always a dream for scientists and engineers in the field ofmaterials science. Plenty of research activities have been performed to approach this dream,including numerical simulations and lab experiments. In this paper, a tensile test on cementpaste is to be simulated virtually on computer. But it is different from previous attemptsbecause we are working at a lower scale, i.e. the micro scale. Although there is a rich set of modeling techniques available to fulfill the task, it is decidedto apply 3D lattice model rather than continuum finite element model to carry out thesimulation because lattice is a discretized model and it would be more preferable to simulatefracture process at micro scale. The cement paste used in the numerical experiment is virtuallysimulated by the cement hydration and microstructure formation model HYMOSTRUC3D. The simulation results reflect the ability of lattice modeling techniques and the addressedprinciples can be used potentially to produce a complete multiscalc simulation.
