A full rate-dependent cohesive law is implemented in the distinct lattice spring method (DLSM) toinvestigate the dynamic fracturing behavior of brittlemate...

Large deformations and geometrically nonlinearity are crucial components of many engineeringproblems. Many numerical methods have been developed to tackle the problem of solving them, suc...

A micro-macro and continuum-discontinuum coupled model and corresponding computer codes are developed in this thesis for rock dynamics study. Firstly, a new micromechanical model for de...

In this work, a four-dimensional lattice spring model is developed for studying the mechanical responses of solids. Our resultsindicate that the Poisson’s ratio limitation of the class...

There are a large number of numerical methods which havebeen applied to rock mechanics and rock engineering. Yet,none can tackle all the problems encountered in rock...

There exist many numerical methods, each of them has its ownadvantages and disadvantages, a further development on numericalmethod is necessary.The future for numerical method are:a)Mu...

The spontaneous crack growth in an infinite domain is studied using the distinct lattice spring model (DLSM).
The kinetic energy, strain energy, crack opening, and crack branching during the crack...
