Abstract

In this article, a novel approach is presented for the simulation of failure processes of structures in extreme events such as earthquakes. Models of material behavior are represented using a Generalized Standard Material framework, and the governing equations are formulated using a Mixed Lagrangian Formalism. This results in the failure simulation computations being cast as different types of mathematical programs. Efficient strategies are devised to solve these mathematical programs in the context of large-scale problems of practical interest. Numerical examples are presented to illustrate the approach.
