    • 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 ...

    • Overbreak risk assessment in the Athens metro TBM tunnels 

      Costopoulos, S. D. (2004)
      Assessment of IBM tunneling conditions and potential for damage in building and archaeological remains is of greatest benefit in resolving problems associated with the construction of the Athens Metro, Greece. In this ...

    • 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 ...
