An interfacial mechanical model for the analysis of earthquake

  • Shen Xin-pu 
  • Zenon Mroz 


In this paper, the shear beam model for analysis of interface failure under joint action of anti-plane shearing and lateral compression and its principal behavior were briefly introduced. The calculation of energy release that is related to the strength of earthquake was presented by using the shear beam model. The sudden increase of load resulted from the "stress locking" at the interface layer in the reloading process was investigated. At the end of the paper, discussions on the mechanism of earthquake were given out.

Key words

interface failure shear beam model stress locking sudden variation of load instability earthquake
