    • Circular tunnel in a gradient elastoplastic rock mass 

      Efremidis G., Chen H., Tsagrakis I., Aifantis E.C., Qi C. (2020)
      This paper attempts to study the mechanical behavior of an elastoplastic rock mass around an underground circular excavation by using gradient theory. The problem (in plane conditions) is reduced to that of a circular hole ...

    • Non-linear 3D simulation of the construction and impounding of a CFRD 

      Dakoulas, P.; Thanopoulos, Y.; Anastassopoulos, K. (2008)
      A general methodology for the non-linear 3D numerical simulation of the phased construction and subsequent reservoir impoundment of a concrete faced rockfill dam built in a narrow canyon is presented. The common characteristic ...

    • Realistic spring block models for earthquake-induced landslides 

      Efremidis G., Avlonitis M., Konstantinidis A., Aifantis E.C. (2015)
      Nowadays, there is an increasing interest for realistic spring-block models capable of addressing precursor phenomena in catastrophic earthquake-induced landslides. By pre-defining the constitutive law between externally ...

    • The sliding surface roughness effect on landslides: A statistical study 

      Avlonitis M., Efremidis G., Konstantinidis A., Aifantis E.C. (2016)
      Spring-block models are a useful tool for modeling avalanche-like dynamics for catastrophic landslides. This paper examines the statistical behavior of the failure of a rock (or soil) slope taking into account the effect ...
