Collateral damage: Evolution with displacement of fracture distribution and secondary fault strands in fault damage zones
[1] We investigate the development of fracture distributions as a function of displacement to determine whether damage around small and large faults is governed by the same process. Based on our own field work combined with data from the literature, we find that (1) isolated single faults with small displacements have macrofracture densities that decay as r, where r is distance from the fault p...
متن کاملInvestigation of seismic damage index due to water level changes in reservoir through nonlinear dynamic analysis under Far-Fault and Near-Fault ground motions
In this study, reservoir water level effects on nonlinear dynamic response of concrete gravity dams are investigated. For this purpose, the nonlinear behavior of the dam concrete is captured using the concrete damage plasticity (CDP) on the non associated flow rule assumption. Water in the reservoir is represented by the Lagrangian (displacement-based) fluid finite elements. The program ABAQUS ...
متن کاملDynamic Assessment: From Underlying Constructs to Implications for Language Teaching
Testing as a general trait of social life has received a great deal of attention by many language teachers and scholars. Throughout history, people have been tested to prove their abilities and experiences or to confirm their capacities. Many authorities have said that assessment and instruction should be integrated as a single and inseparable activity which seeks to understand development by a...
متن کاملEvolving geometrical and material properties of fault zones in a damage rheology model
[1] We discuss numerical simulations of evolving fault zone structures in a 3-D lithospheric model with a seismogenic crust governed by a damage rheology that accounts for large strain associated with permanent brittle deformation. Results for the initial propagation of an existing narrow damage zone subjected to oblique loading exhibit strong asymmetry of the evolving damage with respect to th...
متن کاملUnlocking the effects of friction on fault damage zones
Two-dimensional, numerical models of a linear fault embedded within a linear elastic medium show the generation of off-fault tensile failure that results from inelastic slip along the fault. We explore quasistatic models with slip-weakening friction to assess the effects of spatially and temporally variable friction on the damage patterns. Tensile fractures form where tangential normal stresses...
