Using finite element nonlinear analysis, the dynamic soil pressure on perimeter retainingwalls of structures is investigated. Nonlinear Drucker Prager failure criterion is used to model the soilbehavior in the near field. The far field soil and the middle structure are assumed to behave as linearelastic materials. The soil-wall interface behavior is modeled incorporating nonlinear interfaceelem...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...

Specifying interface for e-business application is becoming complex because of its demanding functionality, a rapid advance in Web technology, and an increasing need of integration with legacy applications. All the recent developments call for a more methodical approach to e-business application interface. In this paper, we propose an interface specification method founded on the concepts of me...

Electronic structure calculations were performed to study the role of misfit dislocations on the structure and chemistry of a metal/oxide interface. We found that a chemical imbalance exists at the misfit dislocation which leads to dramatic changes in the point defect content at the interface - stabilizing the structure requires removing as much as 50% of the metal atoms and insertion of a larg...
