The ability to capture increasingly complex behaviours within a numerical simulation is typically accompanied by an increase in the number of input parameters that must be specified. Inevitably, with additional physics come additional parameters to…
We are excited to announce that we have implemented a mechanically-based model of the rock-reinforcement interaction process. The methodology represents an adaptation of the reinforcement elements first developed for FDEM analysis of reinforced concrete (Zivaljic…
Following up from our previous blog post on 3D FEMDEM Simulations, 3D simulations of a tunnel excavated in a weak rock (resembling properties of a clay shale) are presented here (E=3.8 GPa, ν=0.25, σt=0.41 MPa,…
We have been working on a prototype of three-dimensional FDEM. We’ve implemented most of the critical features into the code, including a quasi-static friction law, Mohr-Coulomb failure criterion, and transversely isotropic elastic constitutive law. We’re…
Mechanical anisotropy: sources and implications The mechanical behaviour of several rocks, such as schists, sandstones, shales and basalts, is characterized by strong stiffness and strength anisotropy . This anisotropy may arise at different spatial scales…
