Procedure to Restart an Interrupted Hybrid Simulation: Addendum to PEER Report 2010/103.

摘要

A hybrid simulation can be intentionally or unintentionally interrupted. This document describes a procedure to restart an interrupted hybrid simulation. The restart of an interrupted hybrid simulation involves restoration of the state of the hybrid model to the state at the beginning of time step at the point at which the interruption occurred (the interrupt time step). Then the hybrid simulation from this point continues and the time steps until the planned simulation break or end occurs. The state of the hybrid model comprises the state of the hybrid simulation integrator (the outer loop), the states of each of the numerical portions (numerical sub-structures) of the model, and the states of each of the physical portions (specimens) of the model. The principal obstacle in restoring these states is that the response of the hybrid model to the applied dynamic excitation depends on the excitation history, and the potential geometric and material nonlinear response of the hybrid model components.
