This paper proposes a simple yet efficient mortar-type method to couple independent finite
element subdomains with intersecting interfaces. In this method, we split the subdomain …

Internal interface problems with strong discontinuities for inclusion‐matrix systems are
common and also challenging in engineering. In this work, a dual mortar embedded mesh …

Theoretical Hertzian contact model is used to numerically study contact area of rock joints
under normal deformation, stress distribution, and spatial variation of aperture during …

Many high concrete-faced rockfill dams (CFRD) are constructed or planned with high
seismic intensity. It is challenging to evaluate the resultant seismic response involving multi …

In contact mechanics computation, the constraint conditions on the contact surfaces are
typically enforced by the Lagrange multiplier method, resulting in a saddle point system. The …

Extrusion damage in the concrete face was widely observed in high concrete-faced rockfill
dams in the last two decades. However, the accurate estimation of the concrete stress …
