This paper develops a two-stage stochastic program and solution procedure to optimize the selection of seismic retrofit strategies to increase the resilience of electric power systems to earthquake hazards. The model explicitly considers the range of earthquake events that are possible and, for each, an approximation to the distribution of damage that is experienced. This is important because e...

The influence of surfaces on the evolution of damage of irradiated Fe is studied using object kinetic Monte Carlo with input from molecular dynamics simulations and ab initio calculations. Two effects are analysed: the influence of traps and the initial distribution of damage in the cascade. These simulations show that for a trap concentration of around 100appm, there are no significant differe...

Abstract With the increase of scale an underground cavern, more and towering side walls are left behind by blasting operation, which leaves a huge hidden danger to structure safety cavern. Taking propagation mechanism damage distribution characteristics vibration along elevation direction as research subject, high wall deep-buried cavern can be obtained comprehensive application theoretical ana...

The present paper focuses on the study of some of the fundamental aspects of the cooperative brittle phenomena and damage growth. This rather complex problem is studied on a simple discretized artifice known as the parallel bar model. The disorder in microstructure is introduced by a statistical description of the distribution of the link rupture strengths. The criteria of the damage growth are...
