Chao Jiang & Gao-Feng ZhaoIn this work, the distinct lattice spring model (DLSM) and the lattice Boltzmann method (LBM) are coupled together to simulate hydraulic fracturing problems. As the DLSM a...

Gao-Feng ZhaoA 3D distinct lattice spring model (DLSM) is proposed where matter is discretized into individual particleslinked by springs. The presented model is different from the conventional lat...

Gao‑Feng ZhaoA fundamental study on the tensile failure of rock is conducted using the three-dimensional lattice spring model. The model covers three aspects: (1) the relationship between the mesos...

GAO-FENG ZHAOA MLS-based lattice spring model is presented for numerical modeling of elasticity ofmaterials. In the model, shear springs between particles are introduced in addition tonormal spring...

Ji‑Jian Lian · Qin Li · Xi‑Fei Deng · Gao‑Feng Zhao · Zu‑Yu ChenIn this work, toppling failure of a jointed rock slope is studied by using the distinct lattice spring model (DLSM). The gravity incr...

Gao-Feng Zhao, Kaiwen XiaThe 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 bra...

GaoFeng ZHAOThere 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)Mul...

G.F. Zhao & N. Khalili & J. ZhaoThere 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...

Gao-Feng ZhaoIn 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...
